ConclusionsnbspnbspBoth Epi-LASIK and LASIK show their own characteristics in increased higher-order aberration at smaller and larger pupil sizes, and may create different effects on optical quality for photopic smaller pupil and scotopic conditions larger pupil. We speculate that the visual performance in the Epi-LASIK group may be better than in the LASIK group for the larger pupil size.

Preoperatively, there was no known risk factor for ectasia but a m between-eye difference in central mean corneal thickness was seen on the optical pachymetry map. Two years postoperatively, bilateral ectasia was diagnosed. This case suggests that abstention or surface ablation treatment may be a safer option than LASIK in patients showing central thickness asymmetry between eyes.Financial Disclosure Neither aut Tue, 23 Nov 2010 18:10:18 +0000 http://www.medworm.com/index.php?rid=3597568&cid=c_13_30_f&fid=38496&url=http%3A%2F%2Fwww.jcrsjournal.org%2Farticle%2FPIIS0886335010003792%2Fabstract%3Frss%3Dyes In this study, CCT was measured by sequential Scheimpflug imaging, spectral-domain anterior segment optical coherence tomography AS-OCT, and ultrasound US pachymetry.Results Each of the groups comprised eyes.
