Is YAG capsulotomy safe?

3 min read

Yes. YAG capsulotomy is a safe and highly effective procedure with a well-established track record spanning over four decades of clinical use. It is one of the most commonly performed ophthalmic laser procedures worldwide, with success rates exceeding 95% for visual restoration and a low overall complication rate when performed within a structured clinical pathway. ³

The procedure’s safety profile reflects several factors: it requires no incisions, involves no intraocular instrumentation, is performed under topical anaesthesia without systemic sedation, and has immediate visual recovery in the majority of cases. ³ Most patients experience no complications beyond transient visual phenomena such as floaters from dispersed capsular debris.

However, YAG capsulotomy is not entirely risk-free. Recognised complications include transient intraocular pressure elevation, which occurs in a proportion of patients within the first few hours post-procedure but typically resolves with short-term topical therapy; vitreous floaters from capsular fragments, which are common but usually settle over days to weeks; and lens pitting if the laser inadvertently contacts the intraocular lens, though this is rarely visually significant. ²

Rare but more serious complications include retinal detachment, with reported incidence ranging from 0.1% to 3.6% depending on patient risk factors such as high myopia, lattice degeneration, or pre-existing vitreoretinal pathology; cystoid macular oedema, occurring in approximately 1% to 2% of cases; and retinal tears. ¹ ² These complications are more likely in eyes with pre-existing risk factors and are not caused by the laser itself but rather by the opening of the posterior capsule and subsequent vitreous dynamics changes. A thorough pre-operative assessment, appropriate patient selection, and structured post-operative monitoring minimise risks and ensure safe outcomes.
