- Abstract
Background: Wet age‐related macular degeneration (AMD) and age‐related cataract are often coexisting causes of visual impairment. Yet, the timing of cataract surgery in wet AMD patients is controversial. Methods: One hundred and eleven eyes of 111 patients with wet AMD underwent cataract surgery at Helsinki University Hospital in Finland during 2014–2018. Best‐corrected visual acuity and central subfield macular thickness (CSMT) were analysed at the time of wet AMD diagnosis, at the last recording prior to cataract surgery and at the first recording and at 1 year after surgery. The cumulative number of antivascular endothelial growth factor (anti‐VEGF) injections at surgery, systemic and topical medication and postoperative anti‐VEGF burden were recorded. Results: Mean age was 78.9 ± 5.6 years at the time of surgery. Central subfield macular thickness (CSMT) significantly decreased (280.1 ± 75.0 µm preoperatively to 268.6 ± 67.6 µm at the first postoperative recording, p = 0.001, and to 265.9 ± 67.9 µm at 1 year, p = 0.003), visual acuity improved (0.70 ± 0.46 logMAR units preoperatively to 0.39 ± 0.40 at the first postoperative recording, and to 0.33 ± 0.34 at 1 year, p < 0.001 for both) and anti‐VEGF treatment intervals lengthened despite the surgery (6.53 ± 2.08 weeks prior to surgery to 7.03 ± 2.23 weeks at 1 year, p = 0.246, and to 7.05 ± 2.57 weeks at the last documented visit, p = 0.035). A CSMT increase of over 30% from the preoperative values was seen in only one case (1 out of 111 eyes, 0.9%). Macular status at surgery, wet AMD subtype, comorbidity of type II diabetes, systemic drugs and topical anti‐inflammatory medication were not associated with macular changes nor with treatment intervals after surgery. The cumulative number of anti‐VEGF injections correlated neither with CSMT change postoperatively (r = −0.051, p = 0.619) nor with CSMT change at 1 year (r = 0.091, p = 0.426). Conclusion: Satisfactory visual outcomes and controlled disease activity were seen in patients with wet AMD undergoing cataract surgery. We found no evidence to support delaying surgery in patients who require it.
