Purpose

To evaluate the rate and time course of posterior vitreous detachment (PVD) induction and progression within the first year after lens surgery (cataract surgery or refractive lens exchange) in myopic eyes, and the effect of patient characteristics on PVD development.

Setting

Prospective, multicenter study at 10 active European study centers: the European Society of Cataract and Refractive Surgeons (ESCRS) MYOpic Pseudophakic REtinal Detachment (MYOPRED) study

Methods

618 eyes with an axial length of ≥25.00 mm scheduled for lens surgery were included. Preoperatively and at each follow-up visit fundoscopy with assessment of Weiss ring and optical coherence tomography (OCT) were performed. At sites participating the ultrasound substudy, patients also received B-scan ultrasonography, if the hyaloid was not visible on OCT. Patients were preoperatively allocated to 2 groups: complete PVD present or not (no PVD, partial PVD, unsure). All patients had a follow-up visit 2 months postoperatively, in the group without complete preoperative PVD additionally 6 months and 1 year after surgery or until presence of complete PVD.

Results

Between May 2017 and August 2019, 618 eyes of 618 patients were included in the MYOPRED study. Sixteen of the patients were excluded or withdrew consent before surgery. Mean age of the study population was 65 ± 10.0 years (range 23 to 92), with 290 (48.2%) females and 312 (51.8%) males. In the study eyes, mean axial length was 26.77 ± 1.85 mm (range 25.00 to 37.04). Fellow eyes were additionally observed. The COVID-19 pandemic affected follow-up visits, leading to delayed and also some missed visits. The preliminary 1-year results will be presented at the meeting.

Conclusions

The first conclusions from the ESCRS MYOPRED study on PVD development after lens surgery in myopic eyes will be presented at the congress. First results regarding the influence of the preoperative PVD status on the incidence of retinal detachment will be available 2023.
