Abstract

Abstract:

BACKGROUND: Intraocular refractive operation with phakic intraocular lens implantation has been used in highly refractive errors patients with over-high diopter and thinner corneal thickness, which has the advantages of reversibility and retain the eye's accommodation.

OBJECTIVE: To evaluate the safety and stability of posterior chamber phakic intraocular lens implantation in comparison with Lasik correction for high myopia.

METHODS: Totally 126 college students with high myopia, 63 males and 63 females, aged (21.87±1.18) years, were randomly divided into test and control groups. In the test group, college students received posterior chamber phakic intraocular lens implantation, while those in the control group were subject to Lasik correction. During 1-year follow-up, naked vision, corrected visual acuity, contrast sensitivity, and postoperative untoward reaction were observed, and the effectiveness and safety indexes were calculated in the two groups.

RESULTS AND CONCLUSION: The effectiveness and safety indexes in the test group were both superior to those in the control group (P < 0.05). After 1 year of follow-up, the contrast sensitivity light and dark environment in the test group was significantly improved, which was also higher than that in the control group. Decreased night vision and glare was found in five cases of the control group and one case of the test group. These findings indicate that posterior chamber phakic intraocular lens implantation is safe and effective that can improve the visual quality in clinic.
