Abstract Details

Purpose:

Surface modification is a useful technology to modify the characteristics of materials. UV/Ozone modification increase the adhesion of intraocular lenses (IOLs) and producing the prevention of PCO. In this study, we evaluate the stability and preventive effects for secondary cataracts using the surface modified IOL.

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 multiple pieces 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 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 at 9 years.

Results:

The densities on surface of SP2 and FY-60AD were 2.1 CCT and 5.5 CCT after 5 years. The center was 1.4 CCT and 2.2 CCT. The posterior was 6.5 CCT and 11.4 CCT respectively. There were statistically significances. The survival rates of YAG laser capsulotomy were 74.8% in SP2 and 13.7% in FY-60AD 9 years postoperatively.

Conclusions:

Surface modified hydrophobic acrylic IOL (SP2) is prevented PCO for more than 9 years. And the material is also stable during the same periods.
