Abstract
|
|
|
This study was performed to evaluate the long-term results and complications after phakic posterior chamber lens implantation to treat high myopia. Ninety-three eyes of 52 patients with high myopia underwent implantation of implantable contact lenses (ICL V4, Staar Surgical Inc.) and were followed for at least 2 years. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, intraocular pressure (IOP), corneal endothelial cell count and postoperative side effects were analyzed. At the last follow-up, UCVA was 20/40 or better in 83 eyes (89.3%). Forty-six eyes (49.5%) were predicted accurately to within ±0.5D, and 68 eyes (73.1%) to within ±1.0D of predicted refraction. Pigment dispersion
was detected in 5 eyes (5.4%) and glaucoma in 3 eyes (3.2%). ICL was removed in 2 eyes (2.2%) due to glare without significant loss of BCVA. No lens opacification or ICL decentration was noted. The results support the long-term safety and efficacy of ICL implantation.
