Purpose:
To report a case of a patient who underwent cataract extraction with intraocular lens (IOL) implantation after previous penetrating keratoplasty (PK) followed by laser in situ keratomileusis (LASIK).
Methods:
Case report and literature review of cataract surgery after PK and LASIK. Cataract surgery was successfully performed in a patient with previous PK and LASIK. This paper outlines our method of calculating the correct power IOL for implant.
Results:
The patient's 1-month postoperative uncorrected visual acuity was 20/70 and best spectacle-corrected visual acuity was 20/30+ with -0.75 +0.50 x 180.
Conclusions:
We report the case of a patient with cataract extraction with IOL implantation after PK and LASIK as well as a description of the method used to calculate IOL power after PK and LASIK. While the IOL selection can be difficult, using the appropriate nomogram can result in good visual outcomes.
