Study of factors for unsuitability of DSAEK in cases of corneal decompensation following cataract surgery.
To evaluate suitability of Descemet's stripping automated endothelial keratoplasty (DSAEK) in cases of corneal decompensation following cataract surgery. In this cross-sectional case series, 90 eyes of 90 patients were evaluated at a tertiary eye care centre. Cases with central corneal scarring or vascularisation, complicated aphakia with significant iris tissue defects and extensive synechaie or posterior segment pathology precluding visual recovery were classified as unsuitable for DSAEK. Of 90 eyes, 42 (46.67%) were unsuitable for DSAEK. Multivariate logistic regression analysis, revealed that patients presenting more than a year after cataract surgery had 7.5-fold odds of being unsuitable for DSAEK as compared with those who presented earlier(OR 7.5; CI 2.0-29.1). Patients with BCVA poorer than 0.06 at initial presentation had 5.0 times odds of being unsuitable for DSAEK (OR 5.0; CI 1.0-24.2). Patients who had prior non-phacoemulsification cataract surgery were 5.5 times less likely to be candidates for DSAEK as compared to those who had prior phacoemulsification (OR 5.5; CI 1.5-19.9) and those with anterior chamber IOL or aphakia were 5.0 times less likely suitable for DSAEK, in contrast to posterior chamber intraocular lenses (OR 5.0; CI 1.3-18.7). The type of cataract surgery, time to presentation and initial visual acuity play a role in determining the suitability of performing DSAEK in patients with corneal decompensation after cataract surgery.
