Short-term Visual Outcomes of Trifocal Diffractive Intraocular Lens Implantation in Patients Who Had Retinal Surgery

Abstract

Purpose: To evaluate the short-term visual outcomes of patients fitted with trifocal diffractive intraocular lens (IOL) who had retinal surgery (either received previously to cataract surgery or simultaneously with cataract surgery). Methods: A retrospective study of 22 eyes received trifocal diffractive IOL implantation. All cases had retinal surgery before or performed simultaneously (combined retinal surgery) with IOL implantation. All eyes received same hydrophobic trifocal diffractive IOL (Acrysof IQ PanOptix; Alcon Laboratories, Inc., Fort Worth, TX, USA). The uncorrected distance visual acuity at 4 m, uncorrected intermediate visual acuity at 60 cm, and uncorrected near visual acuity at 33 cm were evaluated at postoperative 1 week, 1 month, and 3 months. Results: Of the 22 eyes, 13 cases underwent cataract surgery after vitrectomy and 9 cases underwent simultaneous vitrectomy and cataract surgery. The most common cause of vitrectomy was the epiretinal membrane with 13 eyes. There were no significant vision-threatening complications, but one case showed early posterior capsular opacity at 3 months and vision restored immediately after YAG-laser capsulotomy. All post-operative visual acuity values showed statistically significant improvement compared to pre-operative values (p < 0.001). Conclusions: Trifocal IOL is a viable option in cataract patients with a history of retinal surgery or those who require combined retinal and cataract surgery.

Combined Vitrectomy and Cataract Surgery with Enhanced Monofocal Intraocular Lens Implantation

“…Because intermediate vision is becoming more essential owing to the implementation of common tasks, such as using smartphones, computers, and navigation, overall vision satisfaction would have increased as intermediate vision improved following surgery [21,22]. Jung et al [23] used a diffractive trifocal IOL for patients who underwent vitrectomy and reported a satisfaction rate of 53% with intermediate visual acuity. The lower satisfaction than that found in our study is probably due to discomforts from photic phenomenon, including "blurred night vision glare" (71%) and "halo" (41%) after diffractive trifocal IOL implantation [23].…”

In our study, most patients did not experience photic phenomenon.…”
