The aim is to report 2 cases of PRL postoperative complications.
Ophthalmological Institute Fernandez-Vega, Oviedo, Spain.
Posterior chamber phakic intraocular lenses (pIOLs) have become an important option for refractive surgeons, especially after the limitation in the indications of the photoablative procedures as a consequence of the complications and non-desired effects observed and reported in cases of high ametropia. These lens have been demonstrated to provide an excellent visual outcome, although relevant complications have been also described, such as cataract formation, pigmentary dispersion syndrome or pIOLs dislocation. One specific type of posterior chamber pIOLs is the phakic refractive lens (PRL).
Case 1: Woman, 55 years, who underwent to consultation in April 2012 with complaints of visual impairment in both eyes (BE). She underwent refractive surgery in 1994 for myopia of the right eye (RE) -14D and -16D of the left eye (LE), with placement of a PRL lens. Visual acuity (VA) at the time of consultation was RE 8/10 and LE 8/10. Biomicroscopy showed a nasal inferior displacement of the PRL and posterior sucapsular opacity of the crystalline in BE. She underwent PRL lens extraction, phacoemulsification and placement of AT LISA 802 in BE, with final VA RE 10/10 and LE 8/10. Case 2: Woman, 46 years, who underwent in 2001 refractive surgery in BE with placement of a PRL lens (prior refraction RE -24D and LE -22D). On a routine visit in June 2012, had VA of RE 6/10 (-1.00 -1.00x10ẃ) and LE 6/10 (-0.25 -1.00x170ẃ). Biomicroscopy showed PRL with a zero vault at the center and a anterior cortical central cataract in BE. She underwent PRL lens extraction, phacoemulsification and placement of monofocal Acrysoft in BE, with final VA of RE 8/10 (-0.50ẃx90) and LE of 8/10 (afocal).
This lens showed efficacy, stability, and short term safety. However, serious complications such as cataract, PRL descentration, pigment dispersion and acute angle closure glaucoma may occur, and long term safety needs to be evaluated.
