• Study Type: observational
• Target: 40

Brief Summary

Patients who underwent mini-monovision (with bilateral myopic defocus, MM-BMD) surgery for presbyopia correction with monofocal intraocular lenses implantation are supposed to have sufficient uncorrected vision capacity for activities of daily living (ADLs) that require: a) distant vision(DV), (ie. driving), b) intermediate vision (IV), (ie. computer word processing), c) near vision (NV), (ie. book reading). Primary objectives of the study are: 1) the development of a series of tasks in a research setting that will simulate common ADLs that require DV, IV, and NV. 2) the identification of potential correlations of the tasks in the research setting with demographic, clinical and other parameters of the study participants.

Keywords

presbyopia; monovision; activities of daily living,; pseudophakic

Outcome Measures

Primary Outcomes (1)

• Assessment of Visual capacity (VC)

  VC will be measured as the sum of DVC, IVC, and NVC

  1 year following mini-monovision correction surgery

Secondary Outcomes (3)

• Visual capacity for activities that require distant vision (DVC)

  1 year following mini-monovision correction surgery

• Visual capacity for activities that require intermediate vision (IVC)

  1 year following mini-monovision correction surgery

• Visual capacity for activities that require near vision (NVC)

  1 year following mini-monovision correction surgery

Study Arms (1)

monovision

Presbyopic patients that underwent mini-monovision correction with bilateral implantation of monofocal intraocular lenses. Their visual capacity in ADLs will be assessed.

Other: Assessment of visual capacity

Interventions

Assessment of visual capacity OTHER

Visual capacity (VC) is variable comprised by three sub-variables: a) (DVC) Visual capacity for activities requiring distant vision, b) (IVC) Visual capacity for activities requiring intermediate vision, and c) (NVC) Visual capacity for activities requiring near vision. VC will be measured in a scale from 1 to 100 as the sum of the DVC, IVC and NVC

monovision
