Purpose
To evaluate visual outcomes, refractive predictability, contrast sensitivity, and patient-reported visual performance after bilateral implantation of a new diffractive intraocular lens (IOL) (Elana, Carl Zeiss Meditec) in patients with bilateral cataract who previously underwent myopic corneal laser refractive surgery.
Setting
Cornea and Refractive Surgery Department of Hospital Quiron salud Marbella
Methods
This prospective study included 46 eyes of 23 consecutive patients with bilateral cataract and prior myopic laser refractive surgery who underwent uneventful phacoemulsification with bilateral implantation of diffractive presbyopia-correcting IOLs.
Postoperative examinations were performed at 1, 4, 12, and 24 weeks. Outcomes included uncorrected and corrected distance visual acuity (UDVA, CDVA), distance-corrected intermediate visual acuity (DCIVA at 60 cm), distance-corrected near visual acuity (DCNVA at 40 cm), and manifest refraction spherical equivalent (MRSE). Visual acuity was recorded in logMAR units.
At 24 weeks, patient-reported outcomes were evaluated using a standardized PROM questionnaire.
Results
At 6 months postoperatively, monocular UDVA of 0.0 logMAR or better was achieved in 96% of eyes. Distance-corrected intermediate visual acuity (60 cm) of 0.0 logMAR was achieved in 100% of eyes, and distance-corrected near visual acuity (40 cm) of 0.0 logMAR was achieved in 92% of eyes.
Refractive predictability was high, with the majority of eyes within ±0.50 D of emmetropia (add exact percentage if available).
Contrast sensitivity values were within normal limits in 92% of patients at 6 months.
PROM analysis showed that 100% of patients reported satisfaction with distance and intermediate vision, and 92% reported satisfaction with near vision.
Conclusions
Bilateral implantation of this new diffractive IOL in post–myopic laser patients with cataract provided excellent visual acuity across distance, intermediate, and near ranges with high levels of spectacle independence and patient satisfaction. Visual quality, including contrast sensitivity, was maintained, and photic phenomena were minimal. This lens appears to be a safe and effective option for presbyopia correction in patients with previous corneal refractive surgery.
