Abstract
Purpose :
The diagnosis of Dry Eye Syndrome is often based on subjective information. LACRYDIAG (Quantel Medical) is an ocular surface analyzer that utilizes non-contact exams to quickly and accurately diagnosis DES. LACRYDIAG’s FDA approved interferometer performs a quantitative analysis of the aqueous layer and measurement of tear meniscus height. These measurements provide an objective analysis of aqueous deficiency and are valuable to diagnose the cause of DES, offer patients personalized and effective treatment, provide evidence of diagnosis and treatment results, and optimize the outcomes of cataract/refractive surgery.
Methods :
In this study, we utilized the LACRYDIAG interferometer to analyze the aqueous layer and measure tear meniscus height for 25 patients prior to and after cataract surgery. We obtained these measurements 1 week prior to surgery and 1 day, 1 week, and 1 month after surgery for analysis. All measurements were done by three randomized ophthalmic technicians on the same LACRYDIAG machine. All of the surgeries were performed without complications by the same surgeon in the same surgery center.
Results :
We calculated the mean and standard deviations of the tear meniscus height measurements for each patient at each time interval. Analysis of variance (ANOVA) values were calculated using Soper’s analysis of variance calculator (Wiley, New York, NY) with p < 0.05 for significance. We found that there was a statistically significant decrease in tear meniscus height (increase in DES) post-surgery.
Conclusions :
An increased incidence of DES can affect the outcome of cataract surgery. LACRYDIAG’s objective interferometer should be utilized in future studies of the relationship between cataract surgery and DES.
