[Scale for evaluating desirable ametropia or eumetropia].
OBJECTIVE
The purpose of this study is to assess the degree of desirable ametropia in cataract surgery.


METHODS
A scale for evaluation was created. It allows to measure the desired distance for a neat uncorrected vision (desired ametropia) after cataract surgery that presbyopic patients (monocular vision) would like to obtain. This scale helps to calculate the power of the intraocular lens to be implanted. The scale was shown to a series of 50 consecutive presbyopic patients. Refraction was the same in both eyes. The interest of patients in the evaluation of their desirable ametropia was measured on a scale from 0 to 5.


RESULTS
Interest was good for 50% of patients (grade > or = 3). Mean distance desired by patients for a neat uncorrected vision was 1 meter. Preoperative myopia and hyperopia have no significantive influence upon the distance desired for a neat uncorrected vision.


CONCLUSIONS
The choice of the power of the lens implanted during cataract surgery should take into account the patients' desires. An evaluation of the postoperative desirable ametropia should be systematic.
