No. YAG capsulotomy is not painful. The procedure is performed without injections, incisions, or physical contact with the eye beyond the temporary placement of a contact lens on the corneal surface. ³ The laser itself does not cause pain, though patients may perceive brief flashes of light and possibly hear a faint clicking sound as the laser pulses are delivered, but there is no sensation of discomfort from the laser energy.
Preparation for the procedure involves instillation of topical anaesthetic drops, typically proparacaine 0.5% or oxybuprocaine 0.4%, into the conjunctival sac. These drops provide surface anaesthesia sufficient to eliminate any discomfort from placement of the capsulotomy contact lens, which is applied to the cornea to stabilise the eye and provide optical coupling for precise laser focusing. ² Some patients report a mild sensation of pressure from the contact lens, but this is not painful.
During the procedure, which typically takes between two and five minutes, the patient is seated at the laser slit lamp with their chin positioned on a rest and forehead against a support bar, the same configuration used for routine eye examinations. ² The clinician directs the patient to look at a fixation target, focuses the laser on the posterior capsule behind the intraocular lens, and delivers a series of short laser pulses to create the capsulotomy opening.
The experience is comparable to a standard eye examination rather than a surgical procedure. Most patients describe the procedure as straightforward and report no pain during or immediately after treatment. ³ Post-operatively, there is typically no discomfort. Rarely, patients may experience mild grittiness or foreign body sensation if post-operative steroid drops cause temporary surface irritation. ¹
