There is no way to advise you regarding this decision without examining you. There are many criteria that play a role in determining which refractive surgery is ideal for which patient. I would seek consultation with 2 different corneal specialists who perform both procedures and see what is advised for you.
With your prescription you are very likely to be a candidate for laser vision correction. However, I would expect that with both eyes together you are already very close to 6/6. Speak to a local refractive surgeon regarding the risks and benefits of LASIK and then make your decision.
Inflammation causes the appearance of the large vessels on the surface of the eye. This inflammation can be reduced by treating the dry eye appropriately. As the inflammation recedes, the redness should improve. However, dry eye is a chronic condition and the inflammation may return if treatment is stopped. Avoid using any over the counter products which advertize a whitening effect. These drops contain drugs that can worsen the situation when used regularly. See your eye doctor to make sure you are treating the condition appropriately.
Go for a consultation with a refractive surgeron to see whether you are eligible for an additional corrective procedure.
The risk of these complications is low. Steroid drops are necessary to modulate the healing process after PRK. Follow your surgeon's instructions for the best outcome.
