Visual Outcomes and Patient Satisfaction Following Implantation of Enhanced Monofocal IOL in Patients After Corneal Refractive Surgery.

PURPOSE: To determine the visual outcomes and patient satisfaction in patients undergoing cataract surgery who had previous corneal refractive surgery with implantation of enhanced monofocal intraocular lenses (IOLs).

METHODS

This was an ambispective, comparative pilot study conducted at Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, Delhi, India. Thirty-two eyes of 21 patients with a history of prior corneal refractive surgery presenting with cataract in one or both eyes were included in the study. Sixteen eyes were included in each group: enhanced monofocal IOL and standard monofocal IOL. They were evaluated at postoperative 1 day, 1 week, 1 month, and 3 months. The uncorrected and corrected distance (UDVA and CDVA), intermediate (UIVA and CIVA), and near (UNVA and CNVA) visual acuity, contrast sensitivity (CS), and subjective quality of vision were compared between the two groups.

RESULTS

The UDVA was 0.20 ± 0.12 and 0.27 ± 0.10 logarithm of the minimum resolution (logMAR) (P = .08), CDVA was 0.05 ± 0.07 and 0.11 ± 0.10 logMAR (P = .07), UIVA was 0.20 ± 0.13 and 0.31 ± 0.17 logMAR (P = .08), CIVA was 0.10 ± 0.11 and 0.18 ± 0.13 logMAR (P = .05), UNVA was 0.32 ± 0.22 and 0.41 ± 0.13 logMAR (P = .08), and CNVA was 0.06 ± 0.07 and 0.11 ± 0.10 logMAR (P = .09) in the enhanced and standard monofocal IOL groups, respectively. The contrast sensitivity was significantly better in the enhanced monofocal IOL group (1.41 ± 0.18) as compared to the standard monofocal IOL group (1.27 ± 0.16; P = .03). The overall patient satisfaction was higher in the enhanced monofocal IOL group (P = .02).

CONCLUSIONS

Implantation of enhanced monofocal IOLs in patients with cataract and previous corneal refractive surgery provided better contrast sensitivity and overall higher patient satisfaction with comparable uncorrected distance, intermediate, and near visual acuity as compared to the standard monofocal IOL group.
