Visual outcomes of Presbyopic Lens Exchange (PRELEX) with bilateral multifocal intraocular lens implantation in the Indian population.

PURPOSE: To analyze the visual outcomes and patient satisfaction following presbyopic lens exchange (PRELEX) with bilateral implantation of multifocal intraocular lenses (MFIOLs).

METHODS

A single-center, multi-surgeon study involving retrospective analysis of patients with presbyopia who underwent bilateral implantation of MFIOLs with trifocal designs after phacoemulsification or femtosecond laser-assisted cataract surgery (FLACS) at a tertiary eye care hospital in South India. The visual outcomes were assessed at 2 weeks and after 6 months postoperatively, both objectively and subjectively.

RESULTS

A total of 90 eyes of 45 patients with a mean age of 55.16 ± 6.57 years were included. 90% of the patients were hyperopic presbyopes. Postoperatively, the uncorrected distance, intermediate, and near visual acuity (VA) were logMAR 0.04 ± 0.08, 0.03 ± 0.09, and 0.11 ± 0.01, respectively, and remained stable from 2 weeks till beyond 6 months, with 82.22%, 65.55%, and 93.33% achieving a UDVA, UIVA, and UNVA of 20/20 or better at the end of follow-up. A total of 4.44% and 8.88% of the eyes required enhancement by laser refractive surgery and Nd:YAG capsulotomy for posterior capsular opacification, respectively, after a 3-month postoperative period. A total of 95.36% of the patients achieved spectacle independence, with only 15.55% complaining of glare/halos.

CONCLUSIONS

PRELEX with multifocal lens implantation proves to be a safe and effective procedure that yields good visual outcomes along with patient satisfaction, especially in hyperopic presbyopes.
