Multifocal Intraocular Lenses: Neuroadaptation

Quality of life related variables measured for three multifocal diffractive intraocular lenses: a prospective randomised clinical trial

“…However, at 6 months post‐surgery, no significant differences among groups were detected in the percentage of patients that would choose the same IOL again (AT LISA 94.1%, AT LISA tri 93.3%, ReSTOR 100%, P = 0.754). This would suggest that there is a longer period of neuroadaptation for the trifocal lens; however, longer term satisfaction reaches the same levels as for the other IOL groups.…”

Multifocal intraocular lenses: Types, outcomes, complications and how to solve them

“…Therefore, they are classified as refractive [ Figure 1 ], diffractive [ Figure 2 ], or combined. [ 1 4 ]…”

“…They are dependent of pupil dynamics, very sensitive to their centering, may cause halos and glare, and reduce the contrast sensitivity. [ 1 4 ] In addition, some refractive designs include a continuous change in curvature between zones providing functional vision across all distances. [ 6 ]…”

“…[ 1 2 ] As a result, visual symptoms such as halos, glare, and lower contrast sensitivity may occur. [ 3 4 5 ]…”

“…The careful selection of the patient, the knowledge about the IOLs’ design, and their visual performance added to the proper surgical technique and management of possible complications are the key for the success implantation of the multifocal IOLs. [ 1 4 6 ]…”
