Previously, refractive outcomes of cataract surgery have been relatively unpredictable in eyes with unusual biometry, corneal ectasia, a history of refractive surgery, and in pediatric patients. An improved biometric technology may allow an improvement in the refractive outcomes in these clinical ...
Beyond this, the EWC, composed of various water forms, (i) diverse water states may exhibit varying responses to the surrounding environment inside the EWC, and (ii) Wfb may play a crucial role in determining the physical attributes of contact lenses.Cancer patients frequently report experiencing...
These, along with a meta-analysis of recent studies have shown that there seems to be little long-term visual benefit when using FLACS with monofocal lenses. The promised decrease in ultrasound energy required to remove a cataract has not been consistently demonstrated. There is level one ...
in whom a cataractous lens has been removed. The lens mitigates the effects of presbyopia by providing an extended depth of focus. Compared to an aspheric monofocal IOL, the lens provides improved intermediate and near visual acuity, ...
