Presbyopia
Conditions
Brief summary
Patients who underwent bilateral bifocal or trifocal lenses implantation 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 objective of the study is the comparison in a series of ADLs of two cohorts of patients (group 1: subjects with bilateral bifocal lenses implantation, group 2: subjects with bilateral trifocal lenses implantation)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Capacity (VC) | 1 year following surgery | Assessment of Visual capacity (VC) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Distant Visual Capacity (DVC) | 1 year following surgery | Visual capacity for activities that require distant vision (DVC). DVC score will be measured by the performance score in the following ADLs: a) walking specific pathway, 2) walking up stairs, 3) walking down stairs, 4) day-time driving simulation, 5) night-time driving simulation |
| Intermediate Visual Capacity (IVC) | 1 year following surgery | Visual Capacity for activities that require intermediate vision (IVC). VC score will be measured by the performance score in the following ADLs: a) reading ability of movie subtitles, b) reading ability of a predefined computer screen text, c) reading a supermarket badge |
| Near Visual Capacity (NVC) | 1 year follwoing surgery | Visual Capacity for activities that require near vision (NVC). NVC score will be measured by the performance score in the following ADLs: a) cellular phone directory entry search, b) reading of message in a cellular phone, c) reading a medical prescription, d) reading a public phonebook |
