To get the pure clinical results of Yag Laser Posterior Capsulotomy, excluding all the possible factors that might affect the results of that, we performed posterior capsulotomies on after cataracts(118 eyes) by using Q-switched Nd:Yag laser from February 1987 to August 1989 and reviewed the results. Group A is composed of 68 surgical aphakic eyes and group B is composed of 50 Posterior chamber pseudophakic eyes. The results were as follows: 1. One eye in groupA and one eye in group B were congenital cataracts and the others were all adult and senile cataracts. 2. As a result of posterior capsulotomy, 59 eyes(86.8%) in group A and 42(84%) in group B were above 0.5 in corrected visual acuity. 3. On performing, the power setting was under 1.5mJ in 59 eyes(86.8%) in groupA and 40 eyes(80%) in group B. 4. Ocular complications developed in 35 eyes(51.5%) in group A and 15 eyes(30%) in group B. 5. Good preoperative ocular condition may predict good postoperative clinical results. 6. Less energy and pulses in operation combined with less occurrences of vitrous prolapse in group B might be associated with less development of postoperative complications in group B than in group A.

PURPOSE: To compare the safety and efficacy of trabeculectomy using mitomycin C (MMC) with Ahmed valve implantation in pseudophakic glaucomatous eyes. METHODS: We retrospectively reviewed the medical records of 68 pseudophakic glaucoma patients (68 eyes) who had undergone trabeculectomy with MMC (group T, 41 eyes) or Ahmed valve implantation (group A, 27 eyes). Intraocular pressure reduction rates, cumulative probabilities of surgical success, and postoperative complications were compared between two groups. Also, risk factors for surgical failures were analyzed. RESULTS: Intraocular pressure levels at postoperative 12 months were significantly lower in group T (13.8+/-5.1 mmHg) than in group A (19.6+/-6.4 mmHg, p=0.001). Cumulative probabilities of surgical success at postoperative 12 months were significantly higher in group T (95.0%) than in group A (66.2%, p=0.000). No significant differences were noted in the occurrences of complications except hyphema in two groups. We found that a younger age (< or =50 years) and Ahmed valve implantation were significant risk factors for surgical failures. CONCLUSIONS: Trabeculectomy with MMC can be more effective and preferable as a primary surgical option over Ahmed valve implantation for pseudophakic glaucomatous eyes.

Aphakic or pseudophakic glau-oma is known to be at high risk for failure after filtration surgery. The authors retrospectively investigated the results of trabeculectomy in 14 eyes of 14 patients with glaucoma, seven aphakic and seven pseudophakic eyes, which were followed from six months to three years with an average ot 16.5 months. A conventional trabeculectomy without using antifibrotic agents was performed in all the eyes. The site of conjunctival incision was prepared on the virgin area of the conjunctiva; 8 superonasal, 4 inferonasal and 2 inferotemporal approaches. An average postoperative intraocular pressure reduction was 13.4 mmHg. The number of medications decreased in 11 eyes. A spontaneously developed functioning bleb was found in seven eyes. In other four eyes, the filtering bleb was formed with an aid of massage or needling. The remallllllg three eyes did not show a functioning bleb. Postoperative complications included hyphema in 3 eyes, overfiltration in 2 eyes, choroidal detachment in 1 eye, corneal edema in 1 eye and endophthalmitis in 1 eye.

PURPOSE: To assess the reproducibility of circumpapillary retinal nerve fiber layer (cpRNFL) thickness measurement (measurement agreement) and its color-coded classification (classification agreement) by Cirrus spectral domain optical coherence tomography (OCT) in pseudophakic eyes. METHODS: Two-hundred five participants having glaucoma or glaucoma suspected eyes underwent two repeated Cirrus OCT scans to measure cpRNFL thickness (optic disc cube 200 x 200). After classifying participants into three different groups according to their lens status (clear media, cataract, and pseudophakic), values of intra-class coefficient (ICC), coefficient of variance, and test-retest variability were compared between groups for average retinal nerve fiber layer (RNFL) thicknesses and that corresponding to four quadrant maps. Linear weighted kappa coefficients were calculated as indicators of agreement of color code classification in each group. RESULTS: ICC values were all excellent (generally defined as 0.75 to 1.00) for the average and quadrant RNFL thicknesses in all three groups. ICC values of the clear media group tended to be higher than those in the cataract and pseudophakic groups for all quadrants and average thickness. Especially in the superior and nasal quadrants, the ICC value of the cataract group was significantly lower than that of the clear media and pseudophakic groups. For average RNFL thickness, classification agreement (kappa) in three groups did not show a statistically significant difference. For quadrant maps, classification agreement (kappa) in the clear media group was higher than those in the other two groups. CONCLUSIONS: Agreement of cpRNFL measurement and its color code classification between two repeated Cirrus OCT scans in pseudophakic eyes was as good as that in eyes with clear crystalline lens. More studies are required to ascertain the effect of lens status on the reproducibility of Cirrus OCT according to different stages of glaucoma patients.

We investigated pseudophakic residual astigmatism in order to minimize postoperative refractive astigmatism. We examined 110 eyes of 87 patients who had undergone phacoemulsification with small incision and posterior chamber intraocular lens (IOL) implantation. Corneal astigmatism was measured using an autokeratometer (RK-5, canon), refractive astigmatism by manifest refraction, and residual astigmatism by vector analysis. Mean pseudophakic residual astigmatism was +0.47 X 176degrees, predominantly against-the-rule. Variations of pseudophakic residual astigmatism according to sex, age and IOL type were not statistically significant. When performing cataract surgery as refractive surgery, we may consider that pseudophakic residual astigmatism is approximately 0.50D against-the-rule.

6.A Retained Lens Fragment Induced Anterior Uveitis and Corneal Edema 15 Years after Cataract Surgery.

Korean Journal of Ophthalmology 2011;25(1):60-62
A 60-year-old male was referred to the ophthalmologic clinic with aggravated anterior uveitis and corneal edema despite the use of topical and systemic steroids. He had undergone cataract surgery in both eyes 15 years previous. Slit lamp examinations revealed a retained lens fragment in the inferior angle of the anterior chamber, with severe corneal edema and mild anterior uveitis. The corneal edema and uveitis subsided following surgical extraction of the lens fragment. That a retained lens fragment caused symptomatic anterior uveitis with corneal edema 15 years after an uneventful cataract surgery is unique. A retained lens fragment should be considered as one of the causes of anterior uveitis in a pseudophakic patient.

PURPOSE: To report transient corneal edema after phacoemulsification as a predictive factor for the development of pseudophakic cystoid macular edema (PCME). METHODS: A total of 150 eyes from 150 patients (59 men and 91 women; mean age, 68.0 ± 10.15 years) were analyzed using spectral domain optical coherence tomography 1 week and 5 weeks after routine phacoemulsification cataract surgery. Transient corneal edema detected 1 week after surgery was analyzed to reveal any significant relationship with the development of PCME 5 weeks after surgery. RESULTS: Transient corneal edema developed in 17 (11.3%) of 150 eyes 1 week after surgery. A history of diabetes mellitus was significantly associated with development of transient corneal edema (odds ratio [OR], 4.04; 95% confidence interval [CI], 1.41 to 11.54; p = 0.011). Both diabetes mellitus and transient corneal edema were significantly associated with PCME development 5 weeks after surgery (OR, 4.58; 95% CI, 1.56 to 13.43; p = 0.007; and OR, 6.71; CI, 2.05 to 21.95; p = 0.003, respectively). In the 8 eyes with both diabetes mellitus and transient corneal edema, 4 (50%) developed PCME 5 weeks after surgery. CONCLUSIONS: Transient corneal edema detected 1 week after routine cataract surgery is a predictive factor for development of PCME. Close postoperative observation and intervention is recommended in patients with transient corneal edema.
