Abstract Details

Purpose:

To develop an objective measurement tool for tracking presbyopia progress based on age and near visual acuity.

Setting:

Subjects were enrolled in an early feasibility study and separated into 4 categories based on disease progression.

Methods:

Patients were over 40 years of age and showed loss of accommodative ability. Visual outcomes were assessed using the Early Diabetic Retinopathy Study (EDTRS) logMAR charts and wavefront aberrometry. Each patient was evaluated multiple times.

Results:

We classified patients into 4 stages based on disease progression. Stage I Early Presbyopia (38-42 years): difficulty reading 20/40 (J5) or better at near. Stage II Acute Presbyopia (42-48 years): need reading add to see 20/40 (J5) or better at near. Stage III Chronic Presbyopia (48-55 years): progressive use of 0.25 D reading add every year. Stage IV Stable Presbyopia (55+ years): inability to read 20/100 (J10) without reading add. These stages had good correlation with the stages in dysfunctional lens syndrome (DLS).

Conclusions:

We developed an objective measurement tool for tracking presbyopia progress based on age and near visual acuity. This novel classification system has the potential for stage related treatment intervention.
