AIM: To evaluate the safety, efficacy and predictability of the Verisyse/Artisan iris-fixated phakic intraocular lens for correction of high myopia.

METHODS:Totally 58 cases(112 eyes)of the Verisyse/Artisan iris-fixated phakic intraocular lens for correction of high myopia were collected, the preoperative and 3, 6 and 12 months postoperative examination such as uncorrected visual acuity(UCVA), best-corrected visual acuity(BCVA), refraction, endothelial cell, intraocular pressure were observed.

RESULTS: All of 112 eyes were implanted successfully and were followed-up for 1 year. UCVA of all patients were ≥0.5 three months after surgery, 72.3% of eyes with BCVA ≥0.8 six months after surgery, 98% of eyes residual refraction≤±1.00diopters(D)1 year after surgery. There were significant differences between preoperative and 3, 6 and 12 months postoperative spherical equivalent refraction and astigmatism(P<0.05). There were no significant differences between preoperative and 3 and 6 months postoperative intraocular pressure and counts of endothelial cell(P>0.05), but endothelial cell will be loss with the increase of observation time after surgery. Glaucoma, cataract, corneal endothelial decompensation and other serious complications were not found in our study.

CONCLUSION: Verisyse/Artisan iris-fixated phakic intraocular lens for correction of high myopia is effective, safe and predictable. All patients satisfied with the improvement of visual, no serious complications were found, but further clinical observed for a long period of time is necessary.
