The clinical observation of phacoemulsification with intraocular lens implantation to different axial length eyes.

Objective To investigate the clinical effect of phacoemulsification with intraocular lens implantation to different axial length eyes. Methods We selected 200 eyes in 189 cataract patients including 71 eyes of male and 129 of female.They all underwent phacoemulsification with intraocular lens implantation through sclera tunnel incision.Results (l) Visual acuity of one week after the operation was beyond 0.5 in 152 eyes,including 25 eyes of 26.01 - 35.00 mm axial length and 12 eyes of 20-22.00 mm and 115 eyes of 22.01 - 26.00 mm.The percentage were 50% ,57.10% ,89.9% respectively. (2)The postoperative visual acuity beyond 0.5 were in 77.8% and 17.4% respectively of the patients 26.01-30.00 mm axial length and beyond 30.00 mm.The difference was significient(x2 = 18.12,P0.01).(3)No postoperative visual acuity was beyond 0.5 in patients of axial length shortter than 21 mm while 66.7% existed in axial length of 21.01 -22.00 mm.(4)During and after the operation, posterior lens capsule ruptured in 2 eyes and 14 eyes with edema cornea. Conclusion Phacoemulsification with implantation of lOLs to different axial length eyes has the opportunity of quick recovery in vision and stability of refraction. But to patients whose axial length were too long ( 30.00 mm) or too short ( 21.00 mm) ,the effect was bad.
