SLT can sometimes be repeated when its pressure-lowering effect becomes insufficient, but repeat treatment is not automatic. The decision depends on the previous response, current pressure target, drainage-angle findings, and evidence of glaucoma progression. More laser is not necessarily the right next step for every eye.

The glaucoma specialist page explains assessment and treatment options. This guide is for someone who has already had SLT and is being asked to consider it again.

Does a second treatment mean the first one failed?

Not necessarily. A treatment may have helped for a period and later become insufficient. Alternatively, it may never have achieved the required pressure reduction. Those are different histories and should lead to a more specific discussion than simply saying the laser wore off.

Ask for your pressure pattern before and after the earlier SLT. Bring the treatment date and records if another clinic performed it. A single reading today does not show the whole response or explain the current recommendation.

What does the doctor need to reassess?

Ask whether the pressure target is still appropriate and what the optic-nerve and visual-field findings show. The team should explain whether the concern is pressure alone, progression, medication tolerance, or a combination.

Repeat SLT is a treatment decision within glaucoma care, not a stand-alone purchase. Ask why it is preferable to continuing or changing drops, or to another intervention, in your particular situation. The answer should connect the proposed treatment to the reason your current plan is insufficient.

Can you stop drops if another SLT is planned?

Do not stop or change prescribed glaucoma drops unless the treating clinician tells you to. A planned laser date does not establish that pressure is controlled before the procedure or that medication will no longer be needed afterward.

Ask for written instructions for the period before treatment and how any later change will be decided. Clarify whom to contact if you cannot tolerate a drop or cannot obtain it. Quiet symptoms are not reliable evidence that glaucoma is controlled.

Is there a guaranteed number of repeat treatments?

No universal number or duration guarantees success. Your prior treatment and current findings determine whether another session is reasonable. Ask what result would count as adequate and when the team will assess it.

Also ask about the plan if the response is insufficient. Having a next-step discussion does not mean repeat SLT is expected to fail; it means the recommendation accounts for uncertainty. Avoid comparing clinics only by whether they promise to keep you off drops.

What should DFW patients bring to a review?

Bring medication names, prior laser details, pressure records, and available scans or field tests. For a transfer of care to Plano, request those records before the visit so the discussion can use the history rather than reconstruct it from memory.

A glaucoma appointment should end with a clear treatment rationale and monitoring plan. New severe eye pain or sudden loss of vision needs urgent assessment, not a routine repeat-laser booking. The goal is protecting vision through appropriate pressure control, not repeating a procedure simply because it was used before.
