Reply: Analysis of post-DSEK corneal profile and relationship to hyperopic shiftEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We thank Jayaswal et al. for continuing to investigate factors that may contribute to hyperopic shift following DSEK. Concerning the 3 variables they proposed as causes of hyperopic shift, we agree with 2 of them: increased central corneal thickness and decreased posterior radial curvature of the cornea. As addressed in our article, an increase in corneal thickness can decrease the radial curvature of the refractive surface, causing a hyperopic shift. According to Yoo et al., the ratio of central to peripheral (C:P) graft thickness also contributes. Grafts were found to form a meniscus shape (C:P ratio (Source: Journal o...

Analysis of post-DSEK corneal profile and relationship to hyperopic shiftEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We were interested in the article by Holz et al. because in our experience, patients having Descemet stripping endothelial keratoplasty (DSEK) exhibit varying degrees of hyperopic shift; one of our patients showed a +4 diopter shift in the refractive status postoperatively. The authors' explanation for this apparent shift using corneal profiling with anterior segment optical coherence tomography (AS-OCT) is an interesting concept as there seems to be a definite alteration in the posterior profile of the cornea, thus altering the refractive power of the cornea. However, several other factors may contribute to the hyperopic...

Reply: Suture-related complications after cataract surgery: A patient safety issueEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The case presented by Hillier et al. had a clinical course similar to those in our series, and it strengthens our suggestion that exposed sutures should be removed during the early postoperative period. In the letter to which Hillier et al refer, Kelly et al. were commenting on the report of a series of endophthalmitis cases resulting from corneal sutures placed after extracapsular cataract extraction. Specifically, they commented that after small-incision cataract surgery, corneal sutures should be removed prior to discharge from ophthalmic care. We fully agree with this recommendation and believe that our cases support...

Suture-related complications after cataract surgery: A patient safety issueEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The recent case series by Lee et al. highlights the potential morbidity that may result from a retained corneal suture placed during routine cataract surgery via a clear corneal incision. We managed a similar case at our institution. Cataract extraction and intraocular lens implantation via a superotemporal corneal incision had been performed in the right eye of a 67-year-old man 18 months previously at another hospital. The clinical appearance was suggestive of small-incision cataract surgery. On presentation to us, a retained 10-0 nylon corneal suture was found at 10 o'clock, associated with a 1.5 mm stromal abscess and...

Reply: Determining corneal hysteresis and preexisting intraocular pressureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We have seen something similar to the outcomes described by Sergienko and Shargorodska in 2 cases with aphakic glaucoma. The first patient was a 75-year-old man with absolute glaucoma in the right eye caused by the pseudoexfoliation syndrome and spontaneous lens dislocation into the vitreous cavity. At presentation, the IOPcc without medication was 49 mm Hg and the CH was 1.4 mm Hg. After medical treatment was initiated, the IOPcc decreased to 27.3 mm Hg and the CH was 6.3 mm Hg. The fellow eye also had pseudoexfoliative glaucoma. With medication, the IOPcc decreased from 30.9 mm Hg to 23.1 mm Hg and the CH increased fro...

Determining corneal hysteresis and preexisting intraocular pressureEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
The recent publication by Kucumen et al. on the evaluation of corneal biomechanical properties has received attention. The ocular response analyzer (ORA) has become the first choice for in vivo determination of corneal hysteresis (CH). This approach enables critical information to be gained for important issues such as refractive surgery and diagnosis of glaucoma and keratoconus. The authors have made a contribution in a new direction: investigation of the impact of phacoemulsification on corneal properties. They found a decrease in CH in the early postoperative period followed by a slight increase 3 months postoperativel...

Reply: Pupil optics with multifocal intraocular lensesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
As Brown has pointed out, there are other possible explanations of the smaller pupil diameter values we found than those reported in the literature. We appreciate the opportunity to elucidate our study. We chose 5 lux for low-light pupil diameter measurement for several reasons. Before performing this study, we measured the illuminance of a Japanese city at night. Most Japanese roads provide street lamps, and the illuminance under this condition was 5 lux. A previous Japanese report used the same illuminance for scotopic conditions. In addition, under less than 5 lux illumination, patients cannot recognize near targets. We...

Pupil optics with multifocal intraocular lensesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In their study of the pupil diameter of Japanese individuals as a function of age, Nakamura et al. measured 140 eyes of 70 subjects 19 to 80 years of age using an infrared open-view pupillometer (ie, a device that does not obstruct the eye not being measured) at distance and near fixation under 5 lux and 500 lux ambient illumination. They found the mean pupil diameter as a function of age to be consistently smaller than values reported in the literature, and they speculate that this may be due to their unique subject cohort. There are simpler explanations. First, the low-light pupil diameter measurement was at 5 lux, wher...

Reply: Blue light–filtering intraocular lenses and scotopic sensitivityEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We appreciate Dr. Schwiegerling's further discussion of the potential effects of blue light–filtering IOLs on scotopic sensitivity. Our theoretical calculations support the assumption that blue light–filtering IOLs are unlikely to be detrimental to scotopic sensitivity compared with cataract and, at this time, there is no clinical evidence to suggest that scotopic sensitivity is impaired when these IOLs are used.

Blue light–filtering intraocular lenses and scotopic sensitivityEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Cuthbertson et al. provide an excellent review of blue light–filtering intraocular lenses (IOLs). I seek to clarify the effect of these IOLs on scotopic vision. In 2006, I wrote an article illustrating that scotopic illumination increases with blue light–filtering IOLs. In the section titled “Scotopic Sensitivity,” Cuthbertson et al. summarize my paper along with those by Mainster and Sparrow, Werner, and Pons et al. My paper fixes 2 problems in the Mainster and Sparrow paper. First, their ultraviolet-absorbing IOL transmission curves were measured in saline, while the blue light–filtering IOLs were measured i...

November consultation #4Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
In this case, the first priority is a precise and complete orthotics and strabismus examination with a contact lens that simulate a postoperative condition that would leave a refractive error of −0.25 to −0.50 D. This remaining refractive error would provide a larger depth of field. I would tell the patient that presbyopia is unavoidable. After the examination, there are 2 possibilities; that is, vision is satisfactory with the correction or the patient has strabismus. (Source: Journal of Cataract and Refractive Surgery)

November consultation #3Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
This patient must be approached cautiously. In the absence of ectasia, we can assume that the high astigmatism in the left eye is congenital. Unilateral mixed astigmatism often causes a monofixation syndrome with subtle amblyopia. Monofixation syndrome is characterized by suppression of central vision in the eye with the blurred retinal image but maintenance of peripheral binocular fusion. That is likely the case here, with a mild reduction in CDVA to 20/25 in the left eye. The diagnosis of monofixation syndrome can be established by Worth 4-dot testing. Peripheral stimulation shows fusion (the patient sees 4 dots) and cen...

Refractive Surgical Problem: November consultation #1Email this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A 45-year-old man came for consultation seeking refractive surgery; however, he was very worried about the possibility of postoperative eye “deviation.” He has been a soft contact lens wearer for the past 25 years. Visual acuity with the correction (contact lenses and spectacles) he has been using until now is 20/20 in the right eye and 20/200 in the left eye. Refractive evaluation showed an uncorrected distance visual acuity (UDVA) of 20/200 and a corrected distance visual acuity (CDVA) of 20/20 with −2.75 − 1.00 × 10 in the right eye and a UDVA of 20/200 and CDVA of 20/25 with +2.50 − 4.50 × 180 in the left e...

One-year follow-up of toric intraocular lens implantation in forme fruste keratoconusEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present 2 cases of toric intraocular lens implantation for keratoconus: A 55-year-old man with forme fruste keratoconus with a preoperative uncorrected distance visual acuity (UDVA) of 20/800 and a refraction of −6.50−3.00×135 and a 46-year-old man with a claw-shaped topographic pattern, a family history of keratoconus, and a UDVA of 20/800 with a refraction of −5.00−3.00×85. The refraction had been stable for at least 5 years in both patients. Phacoemulsification and implantation of an acrylic toric IOL were uneventful. One year postoperatively, the UDVA was 20/25 in both cases, with a refraction of −0.25�...

Late-onset epithelial ingrowth after laser in situ keratomileusisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We report a case of late-onset epithelial ingrowth that occurred between 17 months and 20 months after an uneventful laser in situ keratomileusis (LASIK) enhancement. The patient denied a history of trauma or symptoms consistent with epithelial disruption. Post-LASIK treatment had included lifting the flap and scraping the epithelial cells followed by placement of corneal flap sutures for several weeks and a bandage contact lens for 3 days. Gradual regression of epithelial cells was noted. The last recorded uncorrected distance visual acuity 24 months after scraping was 20/25. Epithelial ingrowth can occur many months afte...

Surgical flap amputation for central flap necrosis after laser in situ keratomileusisEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
A 52-year-old man had uneventful bilateral myopic laser in situ keratomileusis (LASIK) with planned monovision. Three months later, the left eye was retreated to improve the near vision. On postoperative day 1, the uncorrected distance visual acuity (UDVA) was 0.95 and the patient reported mild ocular pain. Stage 2 diffuse lamellar keratitis was observed. Despite hourly prednisolone instillation, the UDVA decreased to 0.1 and central flap necrosis syndrome was diagnosed. The flap was lifted and stromal bed irrigation performed. One month later, the UDVA was 0.05 with a hyperopic shift of +3.25 diopters and the flap, which ...

Adhesive retention of sodium hyaluronate ophthalmic viscosurgical devices in an acrylic tube model and in porcine-eye corneal endothelium with different irrigation ratesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusion: The stable retention of low-molecular-weight sodium hyaluronate in the acrylic tube model at the low irrigation rate corresponded closely with that observed in the porcine eye. This indicates that low-molecular-weight sodium hyaluronate with the low irrigation rates used in procedures such as microincision cataract surgery may effectively protect corneal endothelial cells against surgical risks.

Conclusions: The small improvement in power-prediction accuracy for exact-power-labeled IOLs decreased in IOLs of 20.00 D or greater. For IOLs of 15.00 to 20.00 D, the increased accuracy (±0.09 D) was statistically significant and could increase predictability of postoperative refractions. Acrylic dioptric power was directly proportional to temperature. (Source: Journal of Cataract and Refractive Surgery)

Customized aspheric intraocular lenses calculated with real ray tracingEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Real ray tracing calculated the exact geometry of custom IOLs to provide the minimum wavefront error, going beyond simple diopter information. Results show spherical aberration can be significantly reduced with aspheric IOLs. However, the limited possible reduction of total HOAs, even perfectly positioned custom aspheric IOLs, may be a reason for the unclear results in studies assessing the potential benefit to visual performance of currently used aspheric IOLs.

Intraocular pressure reduction after phacoemulsification with intraocular lens implantation in glaucomatous and nonglaucomatous eyes: Evaluation of a causal relationship between the natural lens and open-angle glaucomaEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: Intraocular pressure reduction was proportional to preoperative IOP; the highest preoperative IOPs decreased the most and the lowest increased slightly. One-year IOP reductions were sustained for 10 years and were similar in patients of all ages. The IOP reductions were similar to previously reported reductions in nonglaucomatous eyes, indicating that the aging crystalline lens may be a major cause of ocular hypertension and glaucoma and that phacoemulsification with IOL implantation may help prevent and treat adult glaucoma.

Analysis of surface whitening of extracted hydrophobic acrylic intraocular lensesEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Conclusions: The findings strongly suggest that whitening of the hydrophobic acrylic IOL was due to trace water molecules that infiltrate the optic.

Management of cataract caused by inadvertent capsule penetration during intravitreal injection of ranibizumabEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We describe an approach to phacoemulsification of complicated cataract with preexisting posterior capsule tear caused by an intravitreal injection. Careful preoperative planning and attention to fluidics, low bottle height, appropriate incisions, careful hydrodelineation without hydrodissection, avoidance of nuclear rotation, and use of a dispersive ophthalmic viscosurgical device to tamponade vitreous allows safe phacoemulsification with secure posterior chamber intraocular lens implantation. Biaxial microincision cataract surgery can achieve efficient removal of the lens matter without rotating the nucleus, reducing the ...

Simplified technique for combined silicone oil removal during phacoemulsification with standard or toric intraocular lens implantationEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We describe a simple automated technique for silicone oil removal at the time of phacoemulsification combined with standard or toric intraocular lens implantation using the phacoemulsification handpiece in irrigation/aspiration mode. No additional corneal or scleral incisions are needed, and no specialized vitreoretinal instrumentation is required. (Source: Journal of Cataract and Refractive Surgery)

Management of intraoperative floppy-iris syndrome–associated iris prolapse using a single iris retractorEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
We present 2 strategies for managing IFIS-associated iris prolapse. Placement of a single subincisional iris retractor following reposition of the prolapsed iris was the more successful approach. We recommend consideration of this approach in all cases of iris prolapse. (Source: Journal of Cataract and Refractive Surgery)

Teaching surgical skills to residentsEmail this article to a colleague. Save this article to My Clippings. Discuss or comment on this article.
Tell me and I'll forget; show me and I may remember; involve me and I'll understand.Chinese Proverb An often overlooked aspect of resident education is the teaching and evaluation of surgical skills. This is especially important in the most commonly performed ophthalmic surgery—phacoemulsification with intraocular lens (IOL) implantation. The evolution of this intricate surgical procedure has necessitated not only a change in the teaching of surgical techniques to residents, but also an objective way to assess the development of these surgical skills and a way to measure progress and limit complications in resident surg...
