Bob, an Eye Surgeon Ophthalmologist corneal specialist will be able to fit any and all types of contacts that might be appropriate, can evaluate you as a surgical candidate and is a Physician. Some corneal Eye MDs have optometrists (non-physicians) working under their supervision.

Seeing an ophthalmologist who specializes in corneal disease would be a very good idea. But you might also benefit from consulting an optometrist who specializes in fitting contact lenses, especially the newer model/specialty hard contacts. If there is an optometry school in your area, they might be able to refer you to someone knowledgeable about selecting and fitting the best contacts for you.
The reason that almost everyone has switched from hard plastic contact lens to gas permeable contact lens is that with the hard contact lens there was a higher incidence of intolerance, scratched corneas, contact induced irregular astigmatism, neovascularization of the cornea and reduced corneal endothelial cell counts.
So you you can injure your eye with hard contact lens. There is no way I can determine if you have or know whether you will have the problems listed above.
I suggest you put yourself under the care of an Eye MD physician (ophthalmologist) that specializes in corneal disease.
