Traditional imaging design methods can often be ineffective when designing aspheric systems because of the large number of optimization parameters and lack of a good starting point. They are often trapped in a poor local minimum and it can be highly time-consuming to find a good solution in a bumpy design landscape. The simultaneous multiple surface (SMS) method can significantly shorten the time and effort needed to find a desired solution by providing a starting point to optimize close to a good local minimum. We investigate here two design examples and compare them with similar designs obtained via traditional design approaches, as well as global optimization. In the examples considered here, the SMS method combined with a shorter optimization leads to an optimal design.

To evaluate intraoperative anterior chamber depth (ACD) measurements of the aphakic eye to predict the postoperative ACD and compare 2 intraocular lens (IOL) designs.
The advent of laboratory directed evolution yielded a fruitful crosstalk between the disciplines of molecular evolution and bio-engineering. Here, we outline recent developments in both disciplines wi...
To evaluate the effect of intraocular lens (IOL) decentration on optical aberrations with different IOL designs.
The development of new optical designs for intraocular lenses (IOL) is a major challenge for lens manufacturers, as postoperative patient satisfaction is difficult to assess a priori with new concepts...
Ocular parameters have been applied to ophthalmic lens designs in order to satisfy individual wearers. An axial length (AL) of them can be used in individual ophthalmic lens designs. Our aim was to pr...
A comparison of two lens designs manufactured in the same material. The hypothesis is the subjectively rated performance of comfort, vision and lens handling will be better with the modifi...
The aim of this non-dispensing fitting study is to evaluate the subjective comfort, lens handling, lens fitting characteristics and visual acuity of different hydrogel lens designs versus ...
Randomized, controlled, multisite, subject-and observer-masked, 3-arm parallel group clinical trial of 36-month duration to evaluate the safety and efficacy of a novel spectacle lens desig...
This study will compare the on-eye fitting characteristics of three types of contact lenses. Each lens pair will be worn for 30 to 45 minutes before assessment and the results will be comp...
Orthokeratology (ortho-k) is a clinical technique that uses reverse geometry rigid gas permeable contact lens exerting positive pressure on the central cornea to temporary reduce refractiv...
Insertion of an artificial lens to replace the natural CRYSTALLINE LENS after CATARACT EXTRACTION or to supplement the natural lens which is left in place.
The portion of the crystalline lens surrounding the nucleus and bound anteriorly by the epithelium and posteriorly by the capsule. It contains lens fibers and amorphous, intercellular substance.
Incomplete rupture of the zonule with the displaced lens remaining behind the pupil. In dislocation, or complete rupture, the lens is displaced forward into the anterior chamber or backward into the vitreous body. When congenital, this condition is known as ECTOPIA LENTIS.
A type of crystallin that has been found in the lens (LENS, CRYSTALLINE) of certain species of VERTEBRATES. They are inactivated form of PHOSPHOPYRUVATE HYDRATASE.
A type of crystallin that has been found in the lens (LENS, CRYSTALLINE) of certain species of MOLLUSCA such as SQUID and OCTOPUS. It is an inactivated form of aldehyde dehydrogenase.
