Posterior chamber phakic IOL corrects myopia but has high complication rate
Posterior chamber phakic IOL implantation offered predictable and stable refractive outcomes in correcting moderate to high myopia; however, high rates of serious complications occurred, according to a study.
The retrospective study included 53 eyes of 29 patients with moderate to high myopia. All eyes received the PRL posterior chamber phakic IOL (IOL Tech/Carl Zeiss Meditec). Patients’ mean age was 34.6 years.
PC IOL insertion was performed through a 2.75-mm clear corneal tunnel incision on the steepest meridian to reduce postoperative residual astigmatism.
Postoperative outcomes were assessed at 1 day, 1 week, 1 and 3 months, 1 year and annually thereafter. Mean follow-up was 86 months.
Mean uncorrected distance visual acuity improved from 1.37 to 0.14 at final follow-up; mean corrected distance visual acuity improved from 0.10 to –0.01. Both gains were statistically significant (P < .01).
Correction was within 0.5 D of the target in 42 eyes (79.2%) and within 1 D in 50 eyes (94.3%) at 3 months.
Mean endothelial cell loss was 6.9% at 10 years. Slight PC IOL decentration occurred in five eyes (9.4%). One eye (1.8%) had severe decentration and underwent lens extraction at 5 months.
Glaucoma occurred in four eyes (7.5%), clinically significant cortical lens opacification in four eyes and retinal detachment in two eyes (3.8%), according to the authors.
