Postoperative Visual Function of Enhanced Monofocal Intraocular Versus Monofocal Lenses.

Area of Science:

• Ophthalmology
• Refractive Surgery
• Intraocular Lens Technology

Background:

• Cataract surgery involves replacing the clouded natural lens with an artificial intraocular lens (IOL).
• Different IOL designs aim to optimize visual outcomes, including distance, intermediate, and near vision.
• The Vivinex platform offers various IOL options, necessitating comparative performance analysis.

Purpose of the Study:

• To compare the postoperative visual performance of the Vivinex Impress IOL with a standard monofocal IOL (Vivinex MultiSert) on the same platform.
• To evaluate intermediate visual acuity, patient satisfaction, and dysphotopsia incidence between the two IOLs.

Main Methods:

• Retrospective observational study of 100 patients undergoing cataract surgery.
• Fifty eyes received the Vivinex Impress IOL, and 50 received the Vivinex MultiSert IOL.
• Postoperative visual acuity (distance, intermediate, near), contrast sensitivity, and patient-reported outcomes were assessed one month after surgery.

Main Results:

• The Vivinex Impress group showed significantly better uncorrected intermediate visual acuity (UIVA) compared to the MultiSert group (P = .003).
• No significant differences were found in distance visual acuity, near visual acuity, or contrast sensitivity.
• The Impress group experienced a myopic shift from the target refraction; a negative correlation between UIVA and postoperative pupil diameter was noted.

Conclusions:

• The Vivinex Impress IOL provides superior intermediate visual acuity compared to the monofocal MultiSert IOL.
• A slight myopic shift was observed in the Impress group, suggesting preoperative pupil diameter may help select suitable candidates.
• Patient satisfaction and dysphotopsia incidence were similar between the two IOL groups.
