Abstract Details


Refractive lens exchange (RLE) and phakic intraocular lenses (pIOL) implantation are two surgical procedures frequently performed in patients with high refractive errors. The purpose of this work is to compare RLE and pIOL in terms of refractive results, complications and patient satisfaction.


Refractive Surgery Department of Central Lisbon Hospital Center


Prospective study with 48 eyes of 24 patients without cataract and with a refractive error higher than 7 diopters of spherical equivalent. All patients included in the study were 55 years old or younger. Patients were divided in two groups: patients in pIOL group were implanted with iris-claw anterior chamber IOL or posterior chamber phakic IOL; patients in RLE group underwent phacoemulsification and in-the-bag multifocal or monofocal IOL implantation. Visual acuity, Intraocular pressure, corneal endothelial cell count (CECC) and visual function evaluation using VF-14 questionnaire were performed in all patients.


12 patients (24 eyes) were included in pIOL group and 12 patients (24 eyes) were included in RLE group. There were no statistically significant differences between both groups regarding intraocular pressure, CECC and distance visual acuity (p > 0.05). Patients who underwent RLE with monofocal IOL implantation presented the lowest near visual acuity (p < 0.05). Patients in pIOL group had better VF-14 scores, but this difference was not statistically significant.


With advancing technology, pIOL and RLE are valuable procedures with good refractive results and high levels of patient satisfaction. The choice between both is mainly based on patient's age, needs and expectations. FINANCIAL INTEREST: NONE
