SUMMARY

This study analyzed the correlation between ocular dominance and the management of presbyopia with contact lenses using monovision correction. 372 patients were selected and divided into 3 groups. The first group had 236 emmentropic patients; the second with 136 ametropic patients without anisometropia and the third group had 51 ametropic and anisometropic patients. The dominant eye was determined by using the Dolman test. In Group I, 96 patients (40.68 %) showed the need for near vision correction in the dominant eye, 110 patients (46.61 %) needed correction in the non dominant eye and it was indifferent in the case of 30 patients (12.71 %). In Group II, 54 patients (63.53 %) showed the need for near vision correction in the non dominant eye and 31 patients (36.47 %)in the dominant cye. In Group III, 46 patients (90.20 %)needed correction for near vision in the non dominant eye and 5 patients (9.80 %) in the dominant eye.

These results show that a significant number of patients do not always use the dominant eye for distant vision and the non dominant eye for near vision.

Key words: Ocular dominance; Presbyopia; Monovision; Contact lenses.
