Since cataract operation is commonest and basic intraocular operation there are many modified procedures and techniques. Various modified methods of the cataract operation were reviewed and discussed for its advantage and disadvantage according to the specifio eye condition or various types of cataract.

1) In out of a total of 41 cases, the measurement of the corneal curvatures were performed at a preoperative state and postoperative state after 1 month and again after 2 months. 2) The results show that the changes which cccured in the initial stage of the operation tend to become the preoperative state in the healing processes. 3) During the postoperative changes, the changes in the vertical curvatures were shown to be greater than the changes in the horizontal curvatures.

PURPOSE: To evaluate the changes in corneal sensitivity following cataract surgery with a limbal incision. METHODS: The sensitivity threshold was measured in 53 eyes following procedures using a superior limbal incision (42 eyes) or a temporal limbal incision (11 eyes). RESULTS: The corneal sensitivity was significantly lower at the superior and temporal limbal incision sites after surgery than at the other sites (p<0.05). That sensitivity recovered 90% of its preoperative level 30 days post-operative. CONCLUSIONS: Corneal sensitivity decreased following cataract surgery using limbal incision. There were no significant differences in either the rate of decrease or recovery of corneal sensitivity according to the incision sites.

Background: Pediatric cataract is one of the most common preventable cause of childhood blindness worldwide. Early and timely intervention of pediatric cataract is important to maximize the visual outcomes and start prompt visual rehabilitation. Objectives: This study aimed to determine the average time from the day of initial consult at the outpatient clinic to the day of the cataract surgery and compare the effects of delayed surgery on visual outcomes of patients. Methods: This is a retrospective chart review of medical records from January 2015 to June 2022. The dates of the different steps in the process up to the day of intervention were noted and the average interval duration and the total waiting time were determined. Patients operated on within 2 weeks from initial consult was defined as no delay while those operated >2 weeks had delayed surgery. Pre-operative and post-operative best corrected log MAR visual acuity were compared within each group to determine if delay in surgical intervention has a significant effect on the visual outcomes of patients. Results: Median age at initial consult was 4.9 years while median age at surgery was 5.2 years. Ninety-nine (99) patients had developmental cataract and 123 patients had bilateral cataract. Leukocoria was the most common chief complaint (63.45%). Pre-operatively, 94 patients had strabismus, 49 had eye preference, 48 had nystagmus, and 43 had amblyopia in the diagnosis. There was significantly faster admission to cataract surgery during the pandemic compared to pre-pandemic period but there was no difference in the total waiting time. Patients with congenital cataract had the least total waiting time followed by developmental, and rubella cataract. There is no significant difference in visual outcomes between patients operated without delay and with delay. Conclusion There is delayed age at diagnosis and surgery of pediatric cataract patients in the Philippine General Hospital. Early surgery did not reflect better visual outcomes compared to delayed surgery probably due to delay in consultation of patients.

Changes in the state of water in senile cataractous lenses at the different stages of the maturation of cataract were investigated. Senile cataracts of 34 eyes were divided into 4 groups according to degree of lens opacity. Intracapsular cataract extraction was performed and wet weight, dry weight and water content of the cataractous lenses were measured. In incipient and immature cataract, wet weight was 197.4 +/- 20.6mg, dry weight 66.2 +/- 8.2mg and water content 130.6 +/- 15.2mg(66.2%). In mature and hyper mature cataracts, wet weight was 240.8 +/- 39.3mg, dry weight 53.4 +/- 8.3mg and water content 176.3 +/- 37.5mg(73.2%). Wet weight and water content were significantly increased and dry weight was significantly decreased with the maturation of cataract. Sexual differences of wet weight, dry weight and water content were not significant.

The study aimed to investigate effect and experience in this surgical procedure. Subjects are eyes with mild and moderate level of lens laxation. The anterior lens capsule-preserved lensectomy was proved to be high effective. The preserved anterior lens capsule worked as a barrier, prevented the vitreous humor leaking to anterior chamber, limited complications and produced a support for posterior chamber lens implantation lately
