Abstract
Purpose:
To determine the main complications of phakic lenses placement and the incidence of withdrawal of phakic intraocular lens ( PIOL ) secondary to them.
Methods:
A retrospective cohort study was conducted, inlcuding patients with phakic intraocular lens removal associated with complications, obtaining a sample of 65 eyes in 60 patients. We measured and compared each visual capacity and intraocular pressure (IOP) before, during and after the placement of PIOL, the endothelial cell density was measured only prior to placement and prior to removal of PIOL . The results were analyzed using the t student method.
Results:
The average age of PIOL placement was 31.06 years old ( ± 6.8) , being predominant in females with 64.6 %.The most common type of lens asociated with complications was the PIOL artisan with 86%, followed by the PIOL ICL with 9.23 %. The average power of PIOL withdrew was -14.9 (± 3.85). The associated complications were presented in the following order: dislocation or subluxation ( 56.92 %) , corneal decompensation ( 21.53 % ), cataract ( 16.92 % ), ocular hypertension or glaucoma ( 3%) and decreased endothelial count ( 1.5 % ) .The post implant IOL IOP increased in 1.5mmHg (P: 0.014) . The posterior retirement IOL IOP was not changed prior to the withdrawal of the phakic IOL. Endothelial count was significantly lower than prior to the implementation thereof ( 2581 ± 314 vs 1249 ± 508) P : 0.001. The average latency for complication was 5.8 ± 2.6 years.
Conclusions:
The incidence of withdrawal pIOL asociated with complications is 10.5% , being the most frequent complication associated subluxation of the same. We recomend the use of the ICL PIOL in which the fewest complications occurred. However studies that prove his long-term safety are needed.
