To assess the refractive and visual outcomes of extended depth of focus (EDOF) intraocular lenses (IOL) used for cataract surgery in patients with a history of corneal refractive surgery.
Ophtalmopôle de Paris, Hôpital Cochin, Paris, France.
Retrospective consecutive case series including patients with a history of corneal refractive surgery undergoing uncomplicated cataract surgery implanted with an EDOF IOL (Acrysof IQ Vivity; Alcon Inc, Fort Worth, TX). Preoperative assessment included a biometry (IOLMaster; Carl Zeiss Meditec), a corneal topography, and an aberrometry (iTrace; Tracey Technologies Corp., Houston, TX). The Barrett TK True-K formula was used to determine the IOL power targeting emmetropia. A toric IOL was used when the patient presented with a regular astigmatism of more than one diopter. Subjective satisfaction was evaluated on a 0-100 scale.
Seven patients, 4 men and 3 women, representing 12 eyes were included. The median (range) age was 63,4 years [60-82]. Prior refractive surgery procedures were performed 17,4 years ± 9,37 years before cataract surgery. The median axial length was 26.10 [23.6-28.3] mm. The median preoperative best-corrected visual acuity (BCVA) was 0.25 Log of minimum angle of resolution (LogMAR) with a median spherical equivalent (SE) of -1.25 diopters. The mean preop spherical aberrations was 0.33 microns ± 0.30. At one month postoperatively, the mean BCVA was 0,05 ± 0,08 LogMAR and the mean patient satisfaction score was 93.4 ± 5.3.
Prior corneal refractive surgery often generates corneal optical aberrations. Furthermore, IOL calculation are less precise in the concerned patients, for whom EDOF IOL seems to constitute a more satisfactory option.
