Purpose:
To report the safety and efficacy of phakic anterior chamber intraocular lens (PIOL) in myopia.
Setting:
: Ophthalmic Center, Mansoura University.
Methods:
Phakic anterior chamber IOLs were implanted in 70 eyes of 40 consecutive patients with preoperative myopia ranging from 8.00 to-25.00 D. The patients were followed-up for 2 years.
Results:
Postoperative residual refraction was within ±1.00D of desired postoperative refractive error. All eyes (100%} had an increase in best corrected visual acuity (BCVA). No eyes (0%) lost one or more lines of BCVA with a safety index equal 2.1% and efficacy index equal 1,5%. The mean spherical equivalent was stable during the entire follow-up period it was -0.78D ± 0.8 D after 3 months and -0.68 D±0.7D after 2 years. The percentage of cumulative endothelial cell loss after the end of the follow-up period was 4.07%. Pupil ovalization associated with glare occurred in 3 eyes (4.3%). Retinal detachment appeared in 2 eyes (2.9%) and explantation of the IOL was decided in 3 eyes (4.3%) because of cataract development (1 eye) and severe papillary block (2 eyes).
Conclusions:
Implantation of phakic anterior chamber intraocular lens in high myopic eyes resulted in a predictable and stable visual outcome. This type of PIOL appeared to be well tolerated by the corneal endothelium with a low rate of other complications. However a longer follow-up period is recommended.
