A look at the past . . .

A look at the past . . . Dr. P. A. Callan read a paper on the operative treatment of high myopia. . . . At first the operation was limited to young persons with myopia of 16 D and over, and in sound eyes. Since then as low as 9 D has been operated on, and cases with a vision of 1/10 have not been deterrent factors. . . . Prior to the operation, it is not possible to estimate accurately what the resulting refraction will be after the removal of the lens. . . . The objection to any operation on a seeing eye that may lead to blindness is a valid one, but we must conclude that very many of these very high myopia cases are heavily handicapped in the struggle for a bare existence, while not a few are shut out from all means of livelihood for which their previous training fitted them. As regards the method of operating, he stated that the large flap extraction was more likely to be followed by loss of virtreous, intraocular hemorrhage, detachment of the retina, incarceration or prolapse of the iris, not to speak of the greater danger of infection on account of larger wound. In operating by discission and linear extraction, vitreous may be lost and cause detachment of retina by manipulation to remove the swollen lens matter through a small opening. The rapidly swelling lens may produce glaucomatous tension, iritis, etc. Reference: Tyson HH. The operative treatment of high myopia.
