The control of aniseikonia after intraocular lens implantation.

This paper reports a study of postoperative refraction and eikonometry of 50 patients who had unilateral cataract extraction with implantation of a pupil-supported intraocular lens. The mean postoperative aniseikonia (+/- SD) was 1.97 (+/- 1.82). A statistically significant relationship was shown between anisometropia and aniseikonia. Despite aniseikonia of up to 7.8 per cent there were no diplopia problems as the visual system exhibits a high degree of tolerance. It is concluded that aniseikonia can be controlled to within clinically acceptable limits by the simple calculation of intraocular lens power for isometropia.

Routine aniseikonic screening.

Analysis is made from data obtained after screening 1,000 measurable cases attending the eye department of a general hospital consecutively. Some 9 per cent of these patients were found to have a significant degree of aniseikonia. Symptoms of aniseikonia were found to be less common than suggested in the literature; these are limited to 3.6 per cent of the patients surveyed and are absent where the degree of aniseikonia is less than 2 per cent. It is concluded that since the number of patients having a significant degree of aniseikonia is as great as 9 per cent and that the empirical estimation of aniseikonia is unreliable, it is desirable to include eikonometry into the clinical refraction routine.
