ABSTRACT
OBJECTIVE:
To evaluate the efficiency, predictability, and complications after implantation of iris-clawed phakic intraocular lenses (PIOL) for the correction of severe myopia.METHODS:
In this study, 12 cases (21 eyes) with myopia at -11.5 to -21.0 diopters (D) were implanted with Verisyse iris-clawed PIOL with an optical zone of 6.0 or 5.5 mm. All cases have been followed-up for more than 6 months. Uncorrected visual acuity (UCVA), best spectacled-corrected visual acuity (BSCVA), refraction, intraocular pressure, corneal topography, contour of pupil, corneal endothelial count, PIOL IOL position and pigment deposits on the surface of IOL were observed.RESULTS:
The mean follow-up period was (13.2 +/- 2.14) months. After 12 months of follow-up, 17 eyes were investigated and no eyes experienced a loss in BSCVA. UCVA was significantly improved, Five eyes (29.41%) gained 1 line as compared to their preoperative BSCVA, 4 eyes (23.53%) gained 2 lines, 3 eyes (17.65%) gained 3 lines and 2 eyes (11.76%) gained 4 lines. BSCVA was significantly improved, 4 eyes (23.53%) gained 1 or more lines compared to their preoperative BSCVA, 2 eyes (11.76%) gained 2 lines, 2 eyes (11.76%) gained 3 lines, 2 eyes (11.76%) gained 4 lines and 5 eyes (29.41%) gained 5 or more lines. There was no statistically significant difference between pre- and 6 m or 12 m post-operative intraocular pressure and corneal endothelial density (P > 0.05).CONCLUSIONS:
Iris-clawed phakic intraocular lenses (PIOL) is an effective, safe and predictable procedure for the correction of severe myopia. Follow-up study is still required for the evaluation of long-term results.
