When looking at the biometry for our cataract surgery patients, the axial length, keratometry and anterior chamber depth are usually what we gravitate toward.
These values are used in the IOL power calculations, and the anterior chamber depth gives us an idea of the working room while performing phacoemulsification. However, we should also look carefully at the lens thickness.
As the cataract develops and nuclear sclerosis progresses, the anterior-posterior dimension of the human lens increases. A typical cataract surgery patient will have a lens thickness of about 4 mm to (Read more...)
