COLOMBO, Nov. 13, 2019 — Chinese doctors conduct a cataract surgery for a local patient at Lanka Hospital in Colombo, Sri Lanka, Nov. 10, 2019.

The study is helping to explain the common issues driving explantation.

The following article is a part of conference coverage from the American Academy of Ophthalmology 2020, being held virtually from November 13 to 15, 2020. The team at Ophthalmology Advisor will be reporting on the latest news and research conducted by leading experts in ophthalmology. Check back for more from the AAO 2020.

A survey of members of both the American Society of Cataract and Refractive Surgery and the European Society of Cataract and Refractive Surgeons (ASCRS/ESCRS) indicated that the most common complications found with foldable intraocular lenses (IOLs) included dislocation, glare, and optical aberrations. This is according to research results presented at the American Academy of Ophthalmology 2020 annual meeting, held virtually November 13 to 15, 2020.1 

Led by Nick Mamalis, MD, of the John A. Moran Eye Center at the University of Utah, investigators conducted a survey of ASCRS/ESCRS members to evaluate foldable IOL explantations. These results are an update of the 2018 survey, previously presented at the ASCRS 2019 Annual Meeting.2 

Dr Mamalis and colleagues accessed both perioperative data and data relating to both the IOL type and material requiring an explantation. Additional data included patients’ signs, symptoms, and complications requiring an explantations, as well as postoperative results. 

The most common complications associated with 1- and 3-piece acrylic IOLs and 1- and 3-piece silicone IOLs were dislocation and decentration. Survey data indicated that the most common reason for explantation of multifocal IOLs were glare and optical aberrations, followed by incorrect lens power as the third most common complication; IOL calcification was “less frequently noted.”1

Results of this 2019 survey echo similar feedback received in 2018. In that research, Dr. Mamalis and colleagues indicated that the most common foldable IOL complications have “changed little over the past 5 years.”
