To investigate changes in the space area between intraocular lens (IOL) and the posterior capsule during early postoperative period, using ultra-long scan depth (~7.2 mm in air) spectral domain optical coherence tomography (ULOCT).
Five eyes of 5 patients who underwent phacoemulsification and IOL (Acrysof IQ Aspheric Natural IOL) implantation were recruited in this study. A custom built ULOCT was used to calculate the space area between IOL and the posterior capsule at 1 day, 3 days, 1 week and 2 weeks after operation.
The boundaries of IOL and the posterior capsule were clearly visualized using ULOCT in all cases. The mean space area were 0.840 ± 0.598 mm2 at 1 day, 0.485 ± 0.318 mm2 at 3 days, 0.227 ± 0.221 mm2 at 1 week and 0.171 ± 0.115 mm2 at 2 weeks post-operatively. There was significant decrease in the space area at 2 weeks after surgery, compared to that at 3 days post-operatively (post hoc, P < 0.05). There was almost no space between IOL and the posterior capsule in 1 case at 2 weeks post-operatively.
ULOCT is a potential useful tool for observing the space between IOL and the posterior capsule after cataract surgery. The space between IOL and the posterior capsule decreased during early postoperative period.
