One embodiment disclosed is a compact wavefront sensor module to be attached to or integrated with an ophthalmic instrument for eye examination and/or vision correction procedures. The front lens for relaying the wavefront from the eye to a wavefront sampling plane is positioned at the optical input port of the wavefront sensor module. The front lens is shared by the wavefront sensor and the ophthalmic instrument, and the wavefront sensor module can be made very compact while still being able to cover a large eye wavefront measurement diopter range. Another embodiment disclosed is an ophthalmic device for measuring properties of a subject eye including an ophthalmic instrument integrated with the wavefront sensor module.一實施例揭示一種待附接至用於眼睛檢查及/或視力校正程序之一眼科用儀器或與該眼科用儀器整合之小型波前感測器模組。用於將波前自眼睛中繼至一波前取樣平面之前透鏡係定位於波前感測器模組之光學輸入埠處。波前感測器與該眼科用儀器共用該前透鏡，及可使該波前感測器模組非常小型同時仍能涵蓋一較大眼睛波前量測屈光度範圍。另一實施例揭示一種用於量測一病患眼睛之一性質之眼科用裝置，其包含與波前感測器模組整合之一眼科用儀器。
