Purpose:
Providing an objective and subjective evaluation of life quality and satisfaction level of the patients who underwent cataract surgery with implant of bifocal, multifocal and monofocal lenses.
Methods:
Bifocal lenses were implanted in 72 patients, aspheric multifocal lenses in 16 patients, apodized multifocal lenses in 20 patients and Monofocal lenses were implanted in 63 patients. The patients answered a 47 question questionnaire, whose results were evaluated and analyzed.
Results:
The level of satisfaction of the patients implanted with bifocal and multifocal lenses was significantly higher than of those with monofocal lenses (kruskal - Wallis test, p< 0.001 followed by the Dunn test, p< 0.05). As to the comparison of monofocal lenses with bifocal and multifocal lenses, the near vision without correction was considerably lower in patients with monofocal lenses (Z test p< 0.001). The patients with monofocal lenses without correction presented a much lower capacity of reading newspapers or books and as far as manual work than the ones with bifocal and multifocal lenses (Z test, p<0.001).
Conclusion:
The result of this study shows that the patients who received the bifocal and multifocal lenses had a remarkable improvement in their visual acuity for the near vision, being pleased with their general vision without wearing glasses. This is because they were able to read books and newspapers, write checks, fill out forms, do sports, shave or put on make-up, hence having high quality of life without correction.
