Abstract
.) This study was carried on 79 patients (80 eyes) with cataract selected at random from patients attending the ophthalmic outpatient clinic of Mansoura ophthalmology center aiming to compare corneal changes after both phacoemulsification and manual extracapsular cataract extraction. The patients were divided into two groups the first one included 39 patients (40 eyes) who underwent phacoemulsification and foldable 10L, while the second group included 40 patients (40 eyes) who underwent manual ECCE and PMMA small optic PCIOL. Full ophthalmological examination was done including visual acuity, slit lamp biomicroscopy, tonometry, fundus examination, refraction as well as: • Central endothelial cell count measurement usmg specular nucroscopy, • Central corneal thickness measurement using ultrasonic pachymtery. • Corneal surface changes with the resultant postoperative astigmatism using computerized.corneal.topography. All’ cases were’ followed up forJ months postoperatively. Central endothelial cell loss was significantly higher in ECCE group thanphacoemulsificationgroup all through the postoperative intervals, and it stabilized nearly by 3 months postoperatively in both groups. Central corneal thickness measurements reflected the endothelial cell function in the first month postoperatively. in the ECCE group within the first week and gradually returned to almos preoperative values within 2 months postoperatively. By comparing the postoperative astigmatism 111 both gro, significant increase in the resultant corneal astigmatism in the ECCE gil’ was noted which continued to be high despite of its gradual regre < specially after removal of sutures at 2 months, while no signify difference from the preoperative astigmatic values was noted phacoemulsification group
