We reviewed and analyzed the visual acuities achieved and the complications after 949 cataract operations done by ophthalmology residents during the transitional period in which an intracapsular cataract extraction technique was replaced by an extracapsular one. The available records of all patients from 1982 through 1991 were reviewed. Eighteen intracapsular and 896 extracapsular cataract extractions were performed, followed by 906 primary and 43 secondary implants. Posterior capsular rupture occurred in 6.3% of the cases with vitreous loss in 3.4%. Cystoid-macular edema was the most common postoperative complication. The postoperative visual acuity was 20/40 or better in 91% of cases, and it was better than the preoperative visual acuity in 99.5% of cases. With appropriate training and supervision, a resident can achieve good results by doing extracapsular cataract extractions with lens implantations. These results were comparable to those reported by others.

We studied the efficacy and postoperative behavior of a compressible disc posterior chamber intraocular lens in 40 eyes of 33 glaucoma patients. They had a mean follow-up of 12.8 months. Postoperatively, 38 eyes (95%) had a best corrected visual acuity of 20/40 or better. Minor decentration occurred in one case. Early posterior capsule fibrosis (40%) was 50% less than in earlier reports on the rigid Galand disc IOL. Posterior synechias were present in 35% of eyes. Postoperative complications such as pupil capture (0%) and significant posterior capsule opacification (12.5%) were minimized by using this IOL. Closed-loop circular lenses are an attractive alternative to open-loop-supported IOLs in patients with glaucoma.

Over a period of two years we performed combined penetrating keratoplasty, cataract extraction, and intraocular lens implantation in seven children between the ages of 2 and 12 years old. The interval between trauma and the surgery varied from six weeks to six months (3.5 +/- 1.6 months, mean +/- SD). All of the patients had undergone primary repair of corneal perforation. Fresh corneas preserved in McCarey-Kaufman medium were used. The graft size was 7.5 mm with 0.5 mm disparity. Posterior chamber polymethylmethacrylate C-loop lenses were used in all cases. The surgeon's average postkeratoplasty keratometry was used in the calculation of intraocular lens power. The follow-up period ranged from nine to 36 months (18 +/- 9.1 months, mean +/- SD). Six grafts remained clear at the final follow-up. The visual acuity ranged from 20/40 to 20/200 with final astigmatism ranging from 0.5 diopter to 2.0 diopters. One patient developed a retinal detachment 12 months after surgery, which was successfully reattached. One patient, who had preoperative corneal vascularization, had graft rejection, which was treated medically. Our limited series suggests that the triple ocular procedure is a good choice for the treatment of corneolenticular trauma in children. The proper postoperative treatment includes vigorous antiamblyopia therapy and Nd:YAG laser treatment of after-cataracts.

In a preliminary study of 35 patients that had undergone cataract extraction surgery, we compared the visualization of the retinal periphery according to the intraocular lens optic diameter (5, 6, and 7 mm). In all cases, we performed extra-capsular cataract extractions, with a capsulorhexis, and a Posterior Chamber lens. Indirect ophthalmoscopy with scleral depression, and Goldmann lens biomicroscopy were used to visualize the fundus. We found the smaller the optic diameter was, the better the visualization of the peripheral retina was. Indeed there was a wider space between the optic ridge of the lens and the iris. There was also a better transparency of the peripheral capsular bag.

In this series of one surgeon's first 100 cases of endocapsular phacoemulsification cataract surgery (EPECS), believed to be the first truly prospective study of its kind, 86% of patients achieved corrected vision of 6/6 to 6/4; 96% achieved vision of 6/12 or better; and excluding those with pre-existing pathology, 99% achieved 6/12. Posterior capsular rupture occurred in 11 cases, with vitrectomy being required in eight cases. Detailed analysis of the 100 cases is provided.

This prospective study of 96 individuals from 29 families with neurofibromatosis 2, 49 of whom were affected, confirms in an extended series the previously reported association between posterior subcapsular/capsular cataract and neurofibromatosis 2. Posterior subcapsular/capsular cataracts were found in 36 (80%) of the 45 affected individuals (four individuals were excluded from statistical analyses). In addition, the association of peripheral cortical lens opacities with neurofibromatosis 2 was found to be statistically significant. Seventeen of the patients with neurofibromatosis 2 (37.8%) had peripheral cortical cataracts in comparison with none of the unaffected family members (p < 0.0001). In three patients peripheral cortical opacities were present despite the absence of posterior subcapsular/capsular cataracts. These findings support the inclusion of cortical cataracts of early onset, in addition to posterior subcapsular/capsular cataracts, in the diagnostic criteria of neurofibromatosis 2.

An eye with retinal detachment due to breaks in the nonpigmented epithelium in the pars plicata of the ciliary body was reported in a patient who had been infected by endogenous Candida endophthalmitis about 3 years previously. He had no history of ocular trauma or atopic dermatitis, and had undergone extracapsular cataract extraction because of secondary cataract following the endophthalmitis. Three months later, the breaks were detected in his right eye, distributed extensively between the 3:30 and 11:45 o'clock meridians in the pars plicata. The posterior edges of these breaks were pulled to the contracted posterior capsule by zonular fibers. Posterior capsulectomy, vitrectomy, encircling and scleral buckling were performed and resulted in the reattachment of the retina. It was suggested that the ciliary body which had been damaged by endophthalmitis played a role in the development of these breaks.

Posterior chamber intraocular lenses (PC-IOL) were implanted in 42 eyes of 24 severely mentally and physically handicapped patients, and the results were analyzed in comparison with implants in conventional patients. The patient eyes included in this study were 21 eyes of 13 severely mentally retarded patients, 19 eyes of 10 Down's syndrome patients, and 2 eyes of a patient suffering from mitochondrial encephalomyopathy. Surgeries had been performed under general anesthesia and resulted in significant improvement in vision and quality of life. Severe postoperative complications occurred in one of the eyes of two patients. However, the fellow eye of these patients, which also received a PC-IOL implantation, showed an uneventful postoperative course. The present study indicated that cataract surgery with PC-IOL in patients with severe mental and physical handicaps should be considered as an appropriate and promising application in spite of the various technical difficulties in the pre- and postoperative management of these patients. It is stressed that proper calibration of IOL power immediately before surgery under general anesthesia and small incision techniques are essential for a successful operation in patients with severe mental and physical handicaps.

The objective of the investigation was to evaluate implantation of an intraocular lens in patients with cataract and myopia. Posterior chamber intraocular lenses (IOL)+15 D and lens with a length of the axis of 25.00 mm and more were implanted after ECCE or phacoemulsification in the year 1994 in 81 eyes of 71 patients with mean age of 69 years (range 45 - 81 years). The mean length of the axis was 27.05 mm +/- 1.49 mm, the mean value of the IOL was +11.2 +/- 2.83 diopters. Vision of 6/12 and better with supplementary correction was achieved in 62.7% of the eyes during the last check-up examination. The mean refraction value after surgery was -2.11 +/- 1.63 diopters with a range from +2.0 to -6.0 diopters. Surgery of cataract in myopia gravis with implantation of a posterior chamber intraocular lens is fully justified and makes it possible to achieve excellent functional results.

According to the classical diagnostic criteria, the characteristics of 93 cases (182 eyes) of corticosteroid cataract (CSC) were investigated to analyze the relationship between its lens opacity and each of the following items: the duration, total amount of corticosteroid used, visual acuity and glaucoma. Posterior capsular lens opacity can be found in a sensitive patient after four months of administration of corticosteroid. Juvenile and male patients are vulnerable to the disease. Particularly, the variation of III-grade lens opacity is much closely related to the duration and total amount of corticosteroid used. 83.8% of patients were accompanied by glaucoma which may be the main cause of visual impairment of I and II grade lens opacity. The authors propose that CSC be divided into four grades according to the distribution and degree of the lens opacity. It should be alert that CSC might be accompanied by glaucoma.
