One vision problem that people suffer from is hyperopia, in which a person can see things at a distance clearly but not when the objects are up close. The correction of eyesight is done by orthokeratology or ortho-K; which is the reshaping of the cornea. The technique is done with the use of rigid gas-permeable contact lenses over night that will reshape the cornea. The contact lens can also help correct myopia and stigmatism.

In the research Jaume Paume used ten test subjects all suffering from vision problems. With the use of the patient in the trial Jaume Paune developed a lens that was worn at nighttime that corrected the patients with hyperopia. The lens actively applies pressure on the outside of the cornea; which works by reshaping the cornea. Unfortunately the effect is only temporary. The lens must be worn every night to reshape the cornea. The correction to the cornea however will not have lasting affects. The treatment shows promise as an ongoing therapy and an alternative to corrective laser surgery.

The research that Mr. Paune discovered is amazing. It offers patients suffering from vision problems another alternative option then having surgery. The risk with the contact lens is less risky then the patients who undergo surgery. With using the contact lens there is no recovery period or missed work. The lens however is not very cost effective especially since they must be worn every night and replaced from time to time. Personally I feel that this lens still gives patients more options other then surgery.
