Postoperative outcomes using surface modified intraocular lens

Abstract

 

Purpose

 

Evaluation of postoperative outcomes using surface modified intraocular lens (IOL).

 

Methods

 

Subjects comprised 60 eyes that underwent phacoemulsification. Surface modified hydrophobic acrylic IOL (SP2, HOYA) or three piece IOL (FY-60AD, HOYA) were randomly implanted. The mean age of patients is 70.8±8.6. Images were taken using an EAS-1000 (NIDEK) after 1, 2 and 3 year postoperatively. To analyze the whitening (sub-surface nano glistening), glistening and posterior sub-capsular opacification (PCO), The images were photographed from 2 directions (0 and 90 degree) and the densities on surface (whitening), center (glistening) and posterior (PCO) of IOLs were measured and compared. The probability of survival ratio about YAG laser capsulotomy were also measured.

 

Results

 

The densities on surface of SP2 and FY-60AD were 1.59±1.07 CCT and 4.32±1.07 CCT after 3 years. The center were 1.09±1.07CCT and 1.77±0.82 CCT. The posterior were 8.55±7.54 CCT and 16.19±4.70 CCT respectively. There were statistically significances. The ratio of YAG laser capsulotomy were 3.3% in SP2 and 13.3% in PY-60AD.

 

Conclusions

 

Surface modified hydrophobic acrylic IOL (SP2) is prevented PCO. And the development of whitening and glistening are also significantly less.
