Retinitis pigmentosa (RP) is a heterogeneous group of generalized retinal dystrophies often associated with presenile cataract. The existing body of knowledge on the outcome of cataract surgery in patients with RP is based on data from the pre-phaco era. The aim of the study was to review all cataract surgeries performed on patients with RP at the Copenhagen University Eye Clinic Glostrup from 2002 to 2010 in order to evaluate the outcome of cataract surgery in RP patients operated with standard phaco procedure and implantation of an IOL.
Patients with RP were retrospectively identified from a local database containing information about all cataract surgeries performed at the clinic. Pre-, peri- and post-operative information was retrieved from the cataract database. Diagnosis of RP was confirmed from the national Danish Retinitis Pigmentosa Registry.
Thirty-three eyes from 21 patients were included in the study with a mean age at time of surgery of 56.5 years. Corneal oedema was present post-operatively in 4 eyes. Eyes with pre-operative visual acuity better than counting fingers had a doubling in visual resolution after surgery. Eyes with visual acuity worse than counting finger had subjective improvement in visual function but not a marked objective increase in visual acuity.
Older patients and patients with good pre-operative visual outcome had the largest gain in visual acuity post-operatively probably reflecting a better preserved central visual function in those patients.
