PREOPERATIVE AND POSTOPERATIVE KERATOMETRY COMPARISON OF PHACOEMULSIFICATION SURGERY WITH RIGID POSTERIOR CHAMBER INTRAOCULAR LENS IMPLANTATION (PCIOL)

OBJECTIVES:To study and compare pre and post-operative keratometry in phacoemulsication surgery with rigid
posterior chamber intraocular lens (PCIOL) implantation.
METHOD:Hospital based prospective observational study which included 100 presenile and senile cataract cases with superior scleral
incision(5.5mm) phacoemulsication surgery and rigid PCIOL implantation.
The data was analyzed by paired 't' test and 'p' value <0.05 considered signicant. The preoperative and postoperative keratometry was compared
at 6 weeks.
RESULT: There was signicant difference between pre operative and post operative Keratometry (P<0.05) at 6 weeks. Postoperatively majority
of patients developed against the rule astigmatism (76% of patients).
