1. Ocular growth and lens size
Sammanfattning : Ocular axial length growth was investigated with special reference to the influence of crystalline lens and different intraocular lens implants, in human infants and three week-old rabbits. First it was concluded, in a retrospective study of children with bilateral congenital cataract, that lensectomy during the first months of life resulted in almost normal visual development. LÄS MER
2. Fish Lenses : Anatomy and Optics
Sammanfattning : I have investigated some of the biological regulatory mechanisms governing the development of crystalline lenses. I used fish as model animals because they possess optically interesting lenses, while the geometrical simplicity of fish lenses allows for studies that are difficult or impossible with the lenses of other animals.

3. On millimeter and submillimeter wave focal plane arrays implemented with MEMS waveguide switches
Sammanfattning : This thesis presents research towards enabling micromachined millimeter and submillimeter wave focal plane arrays (FPAs). The FPAs operate under the following principle: a switch network consisting of microelectromechanical (MEMS) switches, integrated with micromachined waveguides, is used to feed an array of antenna elements, located in the focal plane of a high-gain quasi-optical system.

4. Inflammatory response after cataract surgery : randomized controlled clinical and laboratory studies of different surgical techniques
Sammanfattning : During the last few years the phacoemulsification technique for cataract extraction has improved considerably. Because of this development phacoemulsification has recently superseded extracapsular cataract extraction (ECCE) as the preferred method. LÄS MER
5. Congenital ectopia lentis : diagnosis and treatment
Sammanfattning : Congenital ectopia lentis (EL) is an ocular condition, which typically causes a high grade of refractive errors, mainly myopia and astigmatism. These might be difficult to compensate for, especially in children, who might develop ametropic amblyopia. LÄS MER
