Clinical Evaluation of Extracapsular Cataract Extraction and Phacoemalsification

ABSTRACT

This study covers comparison and examination of the clinical results of visual acuity recovery, astigmatic change and comparison of patients who underwented extracapsular cataract extraction(ECCE) with insertion of posterior chamber lens(PCL) or phacoemulsification(PE) with insertion of posterior chamber lens. Among 1446 patients who underwented ECCE with PCL or PE with PCL from April. 1983 to December, 1987. 623 patients being followed up their conditions during 6 months were selected. Visual acuity, astigmatism and keratometry were followed up at preoperative and postoperative period of 1 week, 1 month, 2 months, and 6 months. The results were as follows. 1. In PE with PCL, the recovery of visual acuity is earlier than in ECCE with PCL. 2. In PE with PCL, the post operative change of astigmatic axis to the against the rule is more rapid than in ECCE with PCL. 3. In PE with PCL, recovery of astigmatism is earlier than in ECCE with PCL and the amount of astigmatism is lower than in ECCE with PCL.
