PURPOSE: To evaluate visual and refractive outcomes, as well as patient satisfaction after bilateral implantation of an enhanced monofocal intraocular lens (IOL) with emmetropia as a target refraction.
SETTING: San Carlos Hospital, Madrid, Spain.
DESIGN: Prospective, monocentric, noncomparative study.
METHODS: Adults 21 years or older suitable for cataract surgery and with corneal astigmatism <1.50 diopters (D) were bilaterally implanted with the RayOne EMV IOL and followed up for 3 months. Outcomes measures included refraction, monocular and binocular uncorrected distance visual acuity, corrected distance visual acuity (CDVA), uncorrected intermediate visual acuity, distance-corrected intermediate visual acuity (DCIVA), and defocus curve, aberrometry, and satisfaction. Visual symptoms were assessed using the CatQuest-9SF questionnaire.
RESULTS: 50 eyes of 25 patients were included. At month 3, the mean manifest spherical equivalent was -0.39 ± 0.28 D, with all eyes within 1.00 D. Binocularly, uncorrected, at distance, 68% of patients could read ≤0.0 logMAR and 95% ≤0.2 logMAR; at intermediate 59% of patients could read ≤0.1 and 100% ≤0.2 logMAR. Mean monocular CDVA was -0.03 ± 0.06 logMAR and mean monocular DCIVA was 0.28 ± 0.07 logMAR. Binocular defocus curve demonstrated a visual acuity ≤0.2 logMAR over a 2 D range from +1.00 D to -1.25 D. Satisfaction was good in 96% of patients.
CONCLUSIONS: Bilateral implantation of an enhanced monofocal IOL with emmetropia as a target provided excellent binocular CDVA and good DCIVA, with a high level of satisfaction.
