Neural Compensation, Visual Function and Visual Quality After Monofocal or Multifocal Intraocular Lens Implantation

Multifocal intraocular lenses (MIOLs) provide enhanced far and near visual acuity, but they can bring about halos and glare, which are caused by design deficiencies of the IOLs. Compared to monofocal intraocular lens, pseudo accommodation in nonphysiological state may increase the difficulty of neural compensation reconstruction in patients with multifocal intraocular lens implantation. Patients enrolled into the study will be followed for 1 year and will have study visits preoperatively, at 1 week, 3 months, 6 months, 12 months postoperatively.In this trial, we aimed to specify the time of neural compensation reconstruction in patients and to explore the changes of visual function in senile patients with monofocal or multifocal intraocular lens implantation.
