To compare visual results and quality of vision of two multifocal intra ocular lenses (IOL) : REZOOM (AMO) an acrylic hydrophobic refractive multizone versus RESTOR (ALCON) an acrysof hydrophobic acrylic refractive and diffractive IOL with apodization.
36 patients were operated on for unilateral or bilateral cataract with REZOOM or RESTOR IOL. The same type of IOL was implanted for the second eye systematically. The integrity of ocular functions was assessed with clinical examination and a corneal cylinder less than 1 diopter was the condition. Evaluation of visual results was performed between the first and the third postoperative month. The quality of vision was explored in both group (group 1 : REZOOM, group 2 : RESTOR) by a questionnaire dialling with patient satisfaction, presence of halos and glare.
36 patients (18 of the group REZOOM and 18 of the group RESTOR) from 32 to 85 year old with an average of 66 year old in the group 1 and 69 in the group 2 were included in our study. Both groups had good uncorrected distance visual acuity postoperatively : 65 % (group 1) and 85% (group2) recuperated 0.1 logMAR and more. Even for uncorrected near visual acuity we noted excellent results : 81% (group 1) and 84% (group 2) were able to read 0.3 logMAR and more Halos and glare were noted in 20% in the group 1 and 11% in the group 2. All of these patients seemed to tolerate this discomfort. 100% of patients (group 1 and 2) were satisfied with the results of their surgeries.
The multifocality in the surgical treatment of the cataract is a new concept in phase of expansion and tempting in term of patient satisfaction . The high independence from glasses compensate the visual disturbances (halos and glare) but the strong consideration of exclusion criteria, correct patient selection and patient education are necessary.
