[QUOTE="agwagw, post: 2040215, member: 415845"] I concur with Dark Horse, laser to correct vision (instead of glasses) adjusts the shape of the cornea by cutting parts of it away. Laser for retinal treatment doesn't affect the cornea or lens (the wavelengths of the two lasers is different, one heats the cornea, while the other passes straight through to the retina where it couples and heats the target). Not been on this thread for a while, interesting to see the posts. I have been receiving Eylea injections in one eye since the autumn, with significant improvements. Some items for interest: The injections are usually done by the "Nurse Injector" who is very experienced. She uses retractors to keep the eyelids open and she marks the injection point on the surface of the eye so as to avoid blood vessels. While the injections are a bit painful, there has only been a small amount of bleeding if any. However, one day the nurse was ill so the Dr on duty had to take the list. When my turn came he did not use retractors and was trying to hold the eyelids open with one hand and inject with the other. He hit a blood vessel and I had a sub-conjunctival bleed so my eye was bright red for about 10 days (didn't affect the vision thankfully). The anti-VEGF injections will now always be needed as it works by neutralising the growth factors that cause the unwanted blood vessels to grow, new unwanted growth factors will still be produced. There is also evidence that some new blood vessels can reduce with the anti-VEGF, so there is an actual improvement, something laser can never do - it just attempts to stop already problematic vessels from developing further, but damages the retina in the process. In my right eye that had the pan-retinal laser treatment my peripheral vision, especially at night, is poor. In my experience, the laser treatment is much more painful then the injections. Eyelea is more expensive then the others, but it is only needed every two months (once improvements are seen) which comes out to about the same price but with half the number of injections. [/QUOTE]
