Abstract Details

Purpose:

Evaluation of postoperative 5 years outcomes using surface modified intraocular lens (IOL) to prevent posterior capsular opacification (PCO).

Setting:

Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.

Methods:

Subjects comprised 30 patients, 60 eyes that underwent phacoemulsification. The mean age of patients is 70.8±8.6. Surface modified hydrophobic acrylic IOL (SP2, HOYA) or three piece IOL (FY-60AD, HOYA) were randomly implanted. Images were taken using an EAS-1000 (NIDEK) after 1, 2, 3, 4 and 5 year postoperatively, to analyze the light scattering and posterior sub-capsular opacification (PCO). The images were photographed from 2 directions (0 and 90 degree) and the densities on surface (sub-surface nano glistening), center (glistening) and 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 2.1 CCT and 5.5 CCT after 5 years. The center were 1.4 CCT and 2.2 CCT. The posterior were 6.5 CCT and 11.4 CCT respectively. There were statistically significances. The ratio of YAG laser capsulotomy were 3.3% in SP2 and 28.6% in FY-60AD.

Conclusions:

Surface modified hydrophobic acrylic IOL (SP2) is prevented PCO for more than 5 years. And the materials is also stable during the same periods.
