Abstract
Congenitally ectopic lenses need no treatment as long as the vision can be brought up sufficiently by refractive correction through the lens or through the aphakic area. Vision through the lens is generally impossible to correct, because of the deformity of the lens and the marked astigmatism. The correction through the aphakic portion of the pupil depends on the size of this area. It frequently is insufficient. The subluxation of the lens may remain stationary, giving rise to no symptoms beyond the loss of vision; the ectopia may increase in later years, allowing better vision, or total dislocation may occur. More frequently, however, the condition gives rise to cyclitis and glaucoma.When satisfactory vision in a congenitally subluxated lens cannot be obtained by refractive means, operation is indicated. The operations that come under consideration are iridectomy and discission. A satisfactory iridectomy is not easy to perform and does not prevent
