After cataract surgery, treatment with 0.05% cyclosporine A (CsA) resulted in increased tear breakup time, lipid layer thickness, and improved meibocore, according to a study presented during the American Society of Cataract and Refractive Surgery (ASCRS) annual meeting held July 23-27, 2021, in Las Vegas.
Patients (N=41) presenting with cataract and had normal lid position and were free from ocular comorbidities were recruited for this prospective, randomized, double-masked clinical trial. Patients were randomized in a 1:1 ratio to receive 0.05% CsA (n=21) or 0.5% carboxymethyl cellulose (n=20) for 3 months. Efficacy was assessed using the Ocular Surface Disease Index, meiboscore, and Schirmer’s I test and for tear breakup time and lipid layer thickness.
The study cohort comprised patients aged mean 65.94 (standard deviation [SD], 10.35) years.
During follow-up, the clinicians observed that tear break-up time was significantly improved among the CsA cohort (P =.003). At the study conclusion, patients treated with CsA had lower meiboscore (P =.016), increased lipid layer thickness (P =.040), and higher tear breakup time (P =.043).
Independent predictors of postoperative lipid layer thickness included preoperative lipid layer thickness (R2, 0.710; P <.001) and CsA treatment (R2, 0.263; P =.045).
There was a significant correlation between lipid layer thickness and follow-up duration (R2, 0.738; P <.001) suggesting a longer CsA treatment time may more greatly improve lipid thickness outcomes.
This study was limited by its small sample size. Additional longer-term studies are needed to assess whether sustained CsA treatment more greatly improves clinical outcomes.
These data indicated 0.05% CsA more greatly improved tear breakup time, lipid layer thickness, and meibocore following cataract surgery compared with 0.5% carboxymethyl cellulose. A significant correlation was observed between treatment time and lipid layer thickness, indicating 0.05% CsA treatment may be a viable longer-term therapy.
