Visual Function After Implantation Of Multifocal Intraocular Lenses In Dentists

To compare postoperative visual function, particularly during dental procedures, between dentists with multifocal intraocular lenses (IOLs) and monofocal IOLs.

Tokyo Dental College Suidobashi Hospital

 We conducted a survey of dentists who had undergone cataract surgery on both eyes at our hospital. The survey evaluated their visual function during various dental procedures, including restoration device polishing, color shade assessment, and prosthesis fabrication. It also assessed conservative dental treatment, such as differences in color shade between natural teeth and composite resin restorations, pigmentation changes with medication, and oral surgical conditions, such as gingival swelling, redness, bleeding, suppuration, and oral mucosal lesions. The survey also evaluated distant, intermediate, and near vision in daily activities. Spectacle usage and photic phenomena were scored for each situation.

Consent and responses were obtained from 34 participants, who were divided into two groups: multifocal IOL (17 patients) and monofocal IOL (17 patients). There was no significant difference in distant corrected visual acuity (VA) between the two groups (Mann-Whitney U test, p = 0.680). The multifocal group showed significantly lower spectacle dependence in 7 out of 9 items of dental procedures, and there was no significant difference in photic phenomena between the multifocal and monofocal groups. In daily activities, the multifocal group showed significantly lower spectacle dependence of all distances and better near vision. The monofocal group demonstrated significantly lower photic phenomena at near with spectacle (χ² test, P < 0.05).

For dentists, multifocal IOL did not create any specific problems during dental procedures compared to monofocal IOL and reduces spectacle dependence in daily life.
