Abstract Details
Purpose:
To discover a potential application of anterior segment spectral domain (ASSD)-OCT imaging in a study concerning intraocular lens (IOL) opacification in vitro and in vivo and secondary cataract.
Setting:
Department of Ophthalmology, Regional Hospital and University of Pardubice, Czech Republic
Methods:
5 different hydrophilic and hydrophobic acrylic IOLs were displayed in vitro using ASSD-OCT AvantiTM RT-Vue®XR100-2 in normal temperature and after thermal shock caused by the change of temperature (from minus10oC to plus20oC temperature and from plus20oC to plus100oC) in dry and wet (0.9%NaCl) conditions. The clinical group of 26 patients 8-10years after IOL implantation (10 eyes with PC601Y AcryNova- opacity measured by Pentacan 15-20%, 10 eyes with Acrysof SA60AT:opacity in superficial level of IOL by Pentacam 10-15%, 6patients after ZCB00 implantation-IOL opacity by Pentacam 4,2%) and 2 cases of posterior lens capsule abscessus (PLCA) were examined in vivo.
Results:
All hydrophilic acrylic lenses expressed significant but transient opacification after thermal shock in wet conditions. Hydrophobic acrylic IOLs showed diffuse but transient significant opacification after thermal shock only in wet condition. All 10 patients with AcryNovaIOL had significant homogenous scattering in the whole volum of IOL: IOLs were exactly displayed, SA60AT and ZCB00 IOLs were displayed deficiently. Excellent imaging was observed in posterior lens capsule abscessus.
Conclusions:
ASSD-OCT is usable to display the scattering effect of a clouded IOL material both in vitro and vivo and is acceptable for a kvalitative study (screening) of IOL opacification and secondary cataract in clinical practice.
