Abstract:
Lens opacity attenuates the contrast sensitivity and clarity of eye due to scattering of light,which leads to poor vision in cataract patients.Phacoemulsification with primary intraocular lens is the primary surgical approach.Some complaints of vision discomfort commonly occur although the vision acuity is good.It is,therefore,vital for us to seek an objective evaluation system of visual quality after cataract surgery.Contrast sensitivity test and visual questionnaire offer valuable input for this issue.Contrast sensitivity can estimate vision function more accurately to better measure visual impairment preoperatively and vision outcome after cataract extraction.
