Abstract:
A new wavefront sensor and its application in investigating the aberrations in the human eyes are presented here. The refractive errors in human eye are discussed in detail and the need for using a wavefront sensor in quantifying these errors in detail is discussed in the context of modern refractive surgeries. The development of the new wavefront sensor from the existing ones is presented after a brief survey of existing wavefront sensors for the human eye. This wavefront sensor is based on the concept of wavefront's curvature sensing as opposed to the concept of wavefront's slope sensing which is the case for the current wavefront sensors that are being used for the human eye. Detailed theoretical analysis of the wavefront sensor along with its limitations is done. The performance is evaluated using software simulations, experimental analysis with a model human eye and with human eye in vivo. The design and implementation of a Pupillometer and its use along with a wavefront sensor is also presented.
