Intraocular lens design
- aspheric, diffractive, multifocal, trifocal, EDF, toric, accommodating
Lens performance characterization
- power, MTF, wavefront
Photic phenomena
- dysphotopsia, negative dysphotopsia
The dysphotopsia page has a short download about "Negative Dysphotopsia" and "Far Peripheral Vision", and simulations of why peripheral shadows might be "bothersome".
