Purpose
To review objective and subjective assessment methods of the presbyopic disease state. Objective methods include static and dynamic aberrometry, dysfunctional lens syndrome, ocular scatter index (OSI), and biomicroscopy, while subjective methods include visual acuity, refractive add power, and stereopsis.
Setting
Panama Eye Center, Panamá, Panama
Methods
Assessment of presbyopia included wavefront aberrometry using static ray-tracing and dynamic Hartmann-Schack aberrometry. The dysfunctional lens Index (DLI) was measured using the iTrace and ocular scatter was measured using the HD Analyzer. Lens evaluation was performed with biomicroscopy. Visual acuity was measured at 4m, 60cm and 40 cm using ETDRS cards at 85-90 cd/m2 unaided and distance corrected. Manifest refraction at 40 cm determined the refractive add power.
Results
Aberrometry using static and dynamic techniques demonstrated depth of focus curve changes at near: myopic spherical shift compared to distance and widened curves. DLI mildly correlated to OSI, and Add power mildly correlated to age. Distance-corrected near visual acuity (DCNVA) fell with age. Comprehensive results will be presented.
Conclusions
Presbyopia is the manifestation of aging and is associated with objective signs such as lens changes, smaller pupil size, lower DLI and increased OSI as well as subjective signs of reduced DCNVA. Presbyopia is difficult to assess and dynamic aberrometry may demonstrate the active dynamic range of focus response better than other methods.
