Laser assisted cataract surgery methods and devices utilize one or more therapeutic laser beams to form a shaped opening in an anterior lens capsule of an eye while performing a capsulorhexis procedure. A light absorber may be applied to the anterior lens capsule to facilitate laser thermal tissue separation on the lens capsule along a treatment beam path. The relative or absolute reflectance from the eye and optionally from a surgical contact lens may be measured to confirm and optionally quantify the presence of the light absorber prior to application of the treatment beam. 激光辅助白内障手术方法及装置在执行撕囊过程时利用一或多个治疗激光光束在眼睛的晶状体前囊中形成经塑形开口。可将光吸收剂施加到所述晶状体前囊以促进在所述晶状体囊上沿治疗光束路径进行激光热组织分离。在施加所述治疗光束之前，可测量来自所述眼睛及任选地来自手术接触镜的相对或绝对反射率以确认及任选地量化所述光吸收剂的存在。
