I've been diagnosed with a hole in my right eye retina, doctor is advising a laser. is it the right thing to do? what's the best?

Prevent detachment: A hole in the retina carries a risk of the retina coming off (detachment). Laser is a straightforward way of surrounding the hole with scar to prevent it from leaking fluid behind the retina and causing a detachment. It is much less difficult for the patient then the alternative which is operative surgery. If you are really nervous about this then get a 2nd opinion.

Retinal Hole: Laser lessens the risk of this retinal hole becoming a blinding retinal detachment, if you are unsure, get a second opinion from a good retina specialist.

Probably: It depends upon the type of hole. If it is a retinal tear under vitreous traction, the answer is yes. A macular hole would require surgery if your vision is affected. Old small holes within lattice degeneration, for instance, do not need treatment.

Retinal tears laser: Sealing a retinal tear is like putting a fence around it. This hopefully prevents retinal detachment. Laser is often preferred but sometimes cryotherapy is used if laser cannot be used. There can be multiple tears but the process usually, not always, runs its course over 6 weeks. Eyes are checked at increasing intervals thereafter for new untreated breaks which are treated if need be.
