Cataract surgery in Fuchs corneal dystrophy.
OBJECTIVE
Patients with decreased vision due to Fuchs corneal dystrophy and cataract can present with a number of challenges to determine the best surgical option for restoring sight. The ophthalmologist must first distinguish how much of the vision loss is due to the cataract versus the Fuchs corneal dystrophy (FCD) before determining the best surgical course, either cataract surgery alone or cataract surgery combined with full thickness or lamellar keratoplasty. This review will discuss the various techniques and clinical signs to ascertain the source of vision loss and how to use this clinical information to help guide the surgical decision making process in order to optimize the best possible outcome.


RESULTS
Over the last several years, the technique of endothelial keratoplasty has evolved to become an important alternative in the treatment of FCD. Anticipating the correct intraocular lens power for a patient undergoing cataract surgery alone followed by Descemet stripping endothelial keratoplasty (DSEK) or combined cataract surgery with DSEK requires understanding the hyperopic shift that can occur with DSEK and incorporating this correction preoperatively in the intraocular lens power selection.


CONCLUSIONS
New developments in the surgical treatment of Fuchs corneal dystrophy have greatly enhanced our ability to restore vision and reduce the dependence on contact lenses in this genetic disease.
