###Human: I have keratoconus. Do I have other options apart from spectacles? ###Assistant: Hi. Keratoconus is a degenerative eye disorder. This causes corneal thinning and leads to a conical shaped cornea. Soft lenses can be used, the silicone lens with hydrogel based ones in particular. Though RGP (rigid gas permeable) lens are preferred for better vision outcomes, a combination of soft and rigid lenses are also available. If this option fails, then go in for surgical options like microwave thermokeratoplasty.
