Abstract

PURPOSE
To evaluate the clinical outcomes of aspheric hydrophilic acrylic EYELIKE® (Koryo Eyetech Co., Seoul, Korea) intraocular lenses (IOLs).
METHODS
We conducted a retrospective study of 176 consecutive eyes of 160 patients who underwent cataract surgery with implantation of aspheric EYELIKE® IOLs. The following preoperative measurements were collected: slit-lamp examination, uncorrected distance visual acuity (UCDVA), corrected distance visual acuity (CDVA), intraocular pressure (IOP), automatic and manual keratometry, fundus examination, corneal topography, and specular microscopy. The UCDVA, CDVA, IOP, refraction, and slit-lamp examination were evaluated postoperatively at 1 week and at 1, 3, and 6 months. Specular microscopy was also postoperatively conducted at 1 month.
RESULTS
At the 6-month postoperative visit, the mean UCDVA was 0.15 ± 0.23, and the mean CDVA was 0.03 ± 0.07 logarithm of minimal angle of resolution (logMAR). No statistically significant differences were observed among the four groups (postoperative 1 week, postoperative 1 month, postoperative 3 months, and postoperative 6 months) in the manifest spherical equivalent. In total, 74% of IOL Master700 and 54% of A-scan measurements were within ± 0.5 diopters (D) difference from the target refraction, and 95% and 77%, respectively, were within ± 1.0 D from the target refraction. With regard to complications, one case of CME and posterior capsule opacification with decreased visual acuity was detected at month 3 postoperatively; in this case, the CDVA recovered to 0 logMAR with conventional treatment and yttrium aluminium garnetlaser posterior capsulotomy after postoperative 6 months.
CONCLUSIONS
Domestically produced EYELIKE® IOLs had high refraction predictability and stability.
