“What treatment is the safest for glaucoma?”

This question can only be determined based upon what type of glaucoma you have, of which there are many. Eye drops and/or surgery are 2 treatment options that can only be evaluated by a glaucoma specialist. The bottom line is that you want your eye pressures to be as low and as safe as possible. Your optic nerves, corneal thickness, visual field tests, age, health, medications, and refractive status will determine which treatments will be best and which will work for you at the time. Good luck and best wishes.

Lasers or invasive surgery

The answer depends on multiple factors such as the amount of damage, the level of intraocular pressure, the type of glaucoma, coexisting conditions, you ability to adhere to a regimen. The cost and the inconvenience may also be factors in deciding on treatment.
