Dr. Manns currently has two main research interests: a) the optics of the eye, with a focus on understanding the mechanism of accommodation and presbyopia, and b) the development of Optical Coherence Tomography and other imaging technology for ocular biometry. Current projects include:
- Study of the optics of the crystalline lens of the eye and its refractive index gradient. The long-term goal of these studies is to better understand how the continuous growth of the crystalline lens changes the optical quality of the eye. This research will help better understand how refractive errors, such as myopia, develop with age and it will help design better approaches to correct or improve vision.
- Study of accommodation: The long-term goal of these studies is to better understand the mechanism of accommodation and presbyopia, the progressive loss of the ability of the eye to focus on near objects. This research will help develop better surgical and optical strategies for the correction of presbyopia.
- The development of Optical Coherence Tomography and other technology for ocular biometry. The long-term goal of these studies is to develop imaging and biometry devices that will provide quantitative information about the eye that can be used to improve the outcomes of vision correction procedures, including wavefront-guided laser refractive surgery and intraocular lens power calculations for cataract surgery.
