Abstract Details


To evaluate the visual and topographic outcomes in a patient with keratoconus who have undergone cataract surgery and to analyze different methods of keratometry for intraocular lens calculation.


Clinical Ophthalmology Emergency Hospital Bucharest


A 76 years old patient with both eyes keratoconus, right eye ( RE) nuclear and cortical cataract, pseudoexfoliation syndrome, left eye(LE) acute hydrops referred to ophthalmology department with blurred vision in his right eye. At ophthalmological examination the uncorrected visual acuity was counting fingers at 3 meters for RE. Slit lamp examination showed Fleisher ring, cortical and nuclear lens changes in the RE. Pachimetry revealed right eye inferior thickness 426 ยต while topography showed an ectatic cornea.


Phacoemulsification and implant of posterior intraocular lens (IOL) was performed under local anesthesia in the RE. His axial length was obtained with IOL Master and was measured at 24.96 mm while the keratometric values were measured using an autokeratometer, Javal keratometer, an IOL Master and corneal topographer. The IOL power varied significantly from 4 to 12 D, depending on the keratometric value taken for calculation. The IOL power calculation was based on the keratometry values shown by topography and using the SRKT formula a 10 D IOL was placed . One day postoperatively the refraction was -0.75D/-1.75x138.


Cataract surgery requires special considerations and lens power calculations are more challenging in a patient with keratoconus.
