study of posterior chamber intraocular lens implantation

200 cases of extracapsular extraction with Posterior Chamber intra-ocular lens implantation were studied between February, 1988 to April, 1994 at DHQ Teaching Hospital, Abbottabad and were followed up, with a view to measure post-op refractive errors and complications. The procedure was performed either under GA or under Peribulbar anaesthesia using operating microscope, IOL were inserted with the help of air bubble or methyl cellulose. Michol or acetylcholine were used in selected cases. [21% of the patients had visual acuity of 6/6 without any glasses. 72.6% had visual acuity of 6/9 or more with spherical correction of +2D/-2D. 7.8% of the patients developed after cataract which needed yag Laser or capsulotomy] The procedure is treatment of choice for unilateral and senile cataract without any additional complication then seen in routine E.C.C.E. No extra risk of post operative complications is experienced

Refractive error and squint in primary school children

1306 school children were screened for refractive errors and squint between September 1991 and September 1994. 2.60% of the children had abnormal cover test. 7.04% of the children were found to have refractive error. Only 36.95% of the children were aware of their refractive error and using glasses. Myopia was the commonest refractive error amounting to 6.12%. Many of the children examined were not aware of their ocular disease
