Intraocular Lens Power Calculation [PDF]

Journal of Cataract and Refractive Surgery, 1988
Accurate intraocular lens power calculation is an important adjunct to the technique of extracapsular cataract extraction. An increasing number of ophthalmologists now perform preoperative biometry routinely. We studied a group of fifty patients and analysed the accuracy of intraocular lens power calculation using the SRK formula.
