This system of soft lens fitting in conjenction with the backward sloping corneal incision proved satisfactory in 84% of cases and provided good fill-in vision during the postoperative period--that is, until a decision about the type of long-term optical correction was made in each case.
Patients have been very satisfied with these lenses (78% wearing at the end of six months), not the least those with reduced function of the macula. The problems of infection have been discussed, and apart from improvement in lens materials patient selection is of paramount importance. The problem of deposits is presented, but theri elimination will depend on more research into their nature and development, improvement of the material's resistance to this form of attack, and improved lens design to overcome corneal and tear flow problems.
Aphakia may be said to be the best reason for contact lenses. All types are used--(hard) corneal lenses, soft lenses both for daily and extended wear, and even (hard) scleral lenses in exce,tional cases. At present all have their problems so that, although on theoretical grounds an extended wear lens would be ideal, the corneal lens is probably still the lens of choice.
