My Own Experience Of Dysphotopsia During Performing Cataract Surgeries After Multifocal Intraocular Lens Implantation

The aim of this study was to report postoperative effects on daily work and changes in visual function experienced by a cataract surgeon who underwent bilateral multifocal intraocular lens (IOL) implantation.

A 67-year-old male ophthalmologist underwent Same-day sequential bilateral cataract surgery on April 28th, 2023, and Clareon PanOptix Trifocal Toric (Alcon) IOL were implanted in both eyes. CNWTT4 was implanted in the right eye and CNWTT6 was implanted in the left eye. The preoperative uncorrected distance visual acuity (UDVA) was 20/222 in the right eye and 20/133 in the left eye. Postoperatively, UDVA was 20/17 in the right eye and 20/20 in the left eye. Postoperative uncorrected near visual acuity was 20/33 in both eyes. Postoperatively, the surgeon experienced dysphotopsia, such as halos caused by reflections of the operating room ceiling light on the microscope, halos around the YAG laser beam, and concentric rings when light was coming from the side. In addition, the surgeon found some difficulty to place a three-mirror lens on a patient's eye in a dimly lit room. However, these did not interfere with routine clinical practice or surgery.

Multifocal IOL implantation resulted in satisfactory distance and near visual acuity, with no significant impact on the surgeon's daily professional activities.
