Ophthalmic surgeons should treat presbyopia during crystalline lens surgery. Thanks to the quality and advancements in multifocal implant designs effective, high-quality solutions are already available to treat presbyopia in most patients undergoing crystalline lens surgery. Unless the implantation of multifocal IOLs is contraindicated, the treatment solution that may provide spectacle and cont...

Cataract surgery is one of the oldest and the most frequent outpatient clinic operations in medicine performed worldwide. The clouded human crystalline lens is replaced by an artificial intraocular lens implanted into the capsular bag. During the last six decades, cataract surgery has undergone rapid development from a traumatic, manual surgical procedure with implantation of a simple lens to a...

On modeling the causes of presbyopia Weale (2000) presents a theoretical analysis to support his contention for a multifactorial explanation for presbyopia. He suggests that the model supports the notion that the accelerated loss of accommodation relative to other physiological indicators of age is due to the combined effect of normal age related changes in the component elements of the accommo...

Loss of accommodation amplitude during eating (prandial presbyopia) is a rare phenomenon that has been reported in only 1 patient who had had head trauma. We report 2 patients who had not had head trauma and whose accommodative amplitudes, measured by dynamic retinoscopy, became markedly diminished within 1 minute of starting a meal and did not recover for 55-60 minutes. Apart from this abnorma...
