Abstract Details


To assess the visual outcomes of the new quadrifocal IOL (Alcon PanOptix, Fort Worth, Texas, USA).


Brighton & Sussex University Hospitals NHS Trust, Brighton, United Kingdom


This is an observational study of 60 eyes of 64 patients undergoing cataract surgery with new quadrifocal IOL. Single surgeon performed all surgeries under topical anesthesia with superior corneal astigmatism. LogMAR uncorrected distance (UCDVA), near at 40cm (UCNVA) and intermediate at 60cm (UCIVA) were assessed in all cases at the latest follow up visit following surgery. These visual acuities were recorded monocularly and binocularly. Any intraocular and postoperative complications were noted. Patient were asked to grade their day light and night time vision using a subjective grading (Likert Scale: 1 to 4 where 1 was worse and 4 was best)


The mean age and IOL power were 67�7.2years and 23.44�2.78diopters respectively. The mean follow-up was 6�3.1weeks. At latest follow-up, the monocular UCDVA, UCNVA and UCIVA were 0.06�0.1, 0.21�0.10 and 0.21�0.10LogMAR respectvely. Binocularly it was 0.03�0.1, 0.14�0.11 and 0.15�0.12 LogMAR respectively. 6 eyes (6 patients) needed peripheral corneal relaxing incisions for <2.5diopters of astigmatism. One eye developed mild cystoid macular edema at 4 weeks which resolved with treatment. There were no other intra or postoperative complications. The mean subjective score for unaided vision in day light was 4�0.1 and for night time was 3.5�0.3. No patient reported any symptom of dysphotopsia


The new quadrifocal intraocular lens gives good unaided distance, intermediate and near visual acuity. There were no symptoms of dysphotopsia. The patients reported good day and night time unaided visual acuity on subjective scoring.
