Results from lens implantation. A material from four Danish hospitals.

A retrospective evaluation of the results obtained with primary implantation of an iris clip lens, performed in four Danish eye departments, is given. Altogether 203 implants were carried out. The mean age of the patients at the time of operation was 77 years. Seventeen patients had bilateral implantation. Besides the cataract, the age of the patients was main indication for implantation. Contributing indications were monolateral cataract, macular degeneration, and general somatic or psychic incapacity. The incidence of more serious complications was (more than one complication in some eyes): corneal dystrophy 13/203, deposits on the clip lens or in the pupil 18/203, secondary glaucoma 2/203, macular oedema 2/203, late recurrent hyphaema 2/203 and dislocation of the clip lens 6/203. Seven clip lenses were removed. A corrected visual acuity of 6/12 or above was found in 56% of the cases postoperatively. In spite of the complications it is considered justifiable to continue with clip lens implantation in elderly patients, to solve the optical problems following aphakia.
