In this paper, we introduce a novel concept of liquid-actuated aspheric lens (LAL) with a built-in aspheric polydimethylsiloxane lens (APL) to enable the design of compact optical systems with varifocal microscopic imaging. The varifocal lens module consists of a sandwiched structures such as 3d printed syringe pump functionally serves as liquid controller. Other key components include two acry...

Phacoemulsification with an intraocular lens implant is a safe and effective means of correction of visual loss from cataract. The high frequency of this procedure world wide means inevitable direct surgical complications will be numerous even though infrequent. The approach to correcting aphakia following complicated cataract surgery is dependent on multiple factors including the degree to whi...

Sutureless, glueless, scleral fixation of an intraocular lens is a known technique of fixing a lens in the scleral pockets. However, this technique is applied to single-piece and toric lenses instead of 3-piece lenses, allowing the advantage of the use of premium lenses in patients with poor capsular support. Favourable results without complications of pigment dispersion, iris transillumination...
