In the hyperopic eye the cornea and lens are too flat and focus the image to a point in behind of the retina. The image is then seen as a blur. The muscles controlling the lens can overcome some degree of hyperopia, but weaken with age. This is why many hyperopes begin to require distance and near glasses after the age of 30.



After excimer laser correction with Lasik, the cornea is slightly more curved. The image is then clearly focused on the retina.

The result is that the hyperopic patient can see clearly in the distance after excimer laser treatment.
