Outline

Text

Goal: Occasional calcification of hydropilic intraocular lenses (IOL) is seen to be the long term problem, todays even of refractive surgery. Slight calcification can be ignored and YAG capsulotomy is indicated. Problems for easy surgical IOL removal become. Early diagnosis of calcification is necessary. Examination using the anterior segment spectral domain (ASSD)-OCT imaging is able to detect a slight calcification and other opacities in early stage and without mydriasis.

Method: ASSD-OCT AvantiTM RT-Vue®XR100-2 with optic extension was used bot for in vitro and in vivo study.

Results: We have displayed calcifications of 25 IOL after explantation in vitro. Suspected calcification were displayed sucessfully in 3 patients in vivo. We have divided calcification into 3 groups:

1.
superficial homogenous calcification
2.
focal superficial calcification
3.
deep focal calcification of raw material

Conclusion: ASSD-OCT is usable to display the calcification in time and without mydriasis.
