Purpose:To compare the visual outcomes and complications between the eyes receiving retropupillary iris claw intraocular lens (IOL) and scleral-fixated IOL (SFIOL) for post-cataract aphakia.Methods:Medical records of consecutive patients who had iris claw IOL and SFIOL surgery from January 2010 to March 2015, with > 1 year of follow up were retrospectively analyzed. The surgical technique was based on individual surgeon preference. The best-corrected distance visual acuity (BCDVA), previous surgery, surgical technique, and complications were analyzed.Results:Retropupillary iris claw IOL was fixated in 48 eyes (46%) and SFIOL was performed in 56 eyes. Iris claw was performed more frequently at the time of primary cataract surgery (56%) compared to SFIOL (14%) (P < 0.001). At 1 month postoperative, BCDVA was significantly better in the SFIOL group [0.7 ± 0.5 logarithm of minimum angle of resolution (logMAR) in iris claw vs. 0.3 ± 0.2 logMAR in SFIOL, P < 0.001] but this difference did not persist at 1 year (0.4 ± 0.4 logMAR in iris claw vs. 0.3 ± 0.2 logMAR in SFIOL, P = 0.56). Eyes with iris claw IOL experienced significantly more postoperative iritis (17%), intraocular pressure spikes (10%), and ovalization of the pupil (16%).Conclusion:Retropupillary iris claw IOL fixation is as safe as SFIOL for visual rehabilitation of post-cataract aphakia. Visual rehabilitation following iris claw IOL might take longer than SFIOL. Ovalization of the pupil is the commonest adverse effect reported with this type of IOL design.
Purpose: The aim was to study the visual performance of a new refractive extended depth of focus (EDOF) intraocular lens (IOL). Design: Prospective, comparative study. Methods: Consenting patients with age-related cataract willing for bilateral cataract surgery within 2 weeks were implanted with the Supraphob EDOF IOL and those willing for 1 eye surgery were implanted with a monofocal IOL. The uncorrected and best-corrected distance, intermediate and near visual acuity, and contrast sensitivity were evaluated at 1 and 3 months postoperatively. We also inquired about glare, halos, difficulties in night driving, requirement for spectacles, and overall satisfaction with vision. Results: The Supraphob EDOF group (n = 72 eyes) and the monofocal IOL group (n = 54 eyes) were comparable with respect to all preoperative parameters including biometry, visual acuity, and cataract status. The mean age of participants was 58.4 ± 10.6 years. Both groups had similar distance vision but the EDOF group had significantly better intermediate (0.2 ± 0.2 logMAR vs 0.75 ± 0.19 logMAR, P < 0.001) and near vision (median = N6 vs N12, P < 0.001) compared to the monofocal group at 3 months. The contrast sensitivity was similar in both groups. Patients in the EDOF IOL group had much greater satisfaction for intermediate and near vision. Less than 10% patients reported glare, halos, and difficulty in driving at night in the EDOF group. Conclusions: The Supraphob EDOF IOL was effective in improving the distance, intermediate and near vision in majority of patients, and retained good contrast sensitivity with most patients reporting excellent satisfaction.
Microcystic adnexal carcinoma (MAC) is a rare malignancy of sweat glands that has been reported most often on the face in the form of a cutaneous lesion, with the potential for deeper invasion. The synonyms of MAC include sclerosing sweat duct carcinoma, syringomatous carcinoma, and malignant syringoma. Clinically, MAC in the periocular area has been misdiagnosed as basal cell carcinoma, squamous cell carcinoma, or even chalazia. We report a case of MAC presenting clinically as sebaceous gland carcinoma with pagetoid spread for the first time in literature.
Purpose To evaluate the efficacy and safety of micro-pulse trans-scleral diode laser cyclophotocoagulation (MP-TSCPC) in Indian eyes with refractory glaucoma. Methods A prospective interventional short-term study was carried out with relatively small sample size of 55 eyes with refractory glaucoma. All eyes had visual acuity (VA) and intraocular pressure (IOP) measurements at baseline, 1 week (1w), 1 month (1 m) and 3 months (3 m). A single surgeon treated all eyes with recommended MP-TSCPC treatment settings. Surgical success was defined as achieving an IOP between 8–21 mmHg or achieving > 20% IOP reduction. Results The age of participants was 56.98 ± 15.74 years. Our study had more number of males. VA (in logMAR) at baseline was 1.38 ± 0.99. VA was 1.43 ± 0.93 at 1w, 1.47 ± 0.94 at 1 m and 1.47 ± 0.96 at 3 m (p > 0.05 for all). IOP (in mmHg) at baseline was 30.38 ± 10.70. IOP was 15.72 ± 6.85 at 1w, 16.98 ± 8.72 at 1 m and 17.60 ± 8.40 at 3 m (p < 0.001 for all). At 3 m, 49 (89.1%) eyes had surgical success. Surgical success was lesser in primary open angle glaucoma (p = 0.03). IOP at baseline showed significant correlation with percentage reduction in IOP at each review (p < 0.05). Use of glaucoma medication reduced from 2.94 ± 0.98 to 2.01 ± 1.16 at 3 m (p < 0.001). At 3 m, hypotony was noted in 4 (7.3%) eyes and reduction in visual acuity was seen in 15 (27.3%) eyes. Conclusion Initial experience in Indian eyes has shown that MP-TSCPC is safe and effective for refractory glaucoma. Patients can expect significant IOP lowering along with reduction in number of topical medications required for control of IOP.
An innovative intraocular lens (IOL), the CM-T Flex IOL, was used to correct surgical aphakia without disturbing a functioning filtering bleb. A 66-year-old man presented with aphakia in the left eye. Cataract extraction and trabeculectomy was performed in the left eye 2 years previously elsewhere. Corrected distance visual acuity (CDVA) in the left eye was 6/18, and, on examination, it showed a filtering bleb that encroached on the limbus and superior cornea. The cornea was clear with a deep anterior chamber. Retinal examination was normal. Disc cupping was noted with a cup-to-disc ratio of 0.8. Refractive correction was performed by implanting the CM-T Flex IOL. This IOL has a unique design that eliminates the need for maneuvering the IOL haptics extraocularly. It entails a simple grasp, exteriorize, and release technique that anchors the IOL firmly to the scleral bed. At 6 months, CDVA in the left eye was 6/9 with a stable, centered IOL.
