Astigmatism after extracapsular cataract extraction

ABSTRACT

Astigmatism following extracapsular cataract extraction was not studied in the literature before. An attempt was made to study the type and amount of astigmatism after extracapsular Cataract extraction. Twenty cases of cataract were operated upon using the micro-irrigation-aspiration technique adopted in Alexandria University, the same technique of incision and wound closure was used in every case. Preoperative astigmatism was measured. Postoperatively, astigmatism was measured as early as possible and then weekly for at least 6 weeks. Early post operative astigmatism was high [about 5.0 D] and was mostly of the direct type. However, it decreased gradually with time and was shifted mainly to the inverse type
