Tear Film Meniscus Evaluation By Anterior Segment Optical Coherence Tomography After Phacoemulsification In Diabetics And Non-Diabetics V

The purpose of this study is to compare  the tear film menisucus by anterior segment optical coherence tomography  in  eyes  after Phacoemulsification in  diabetic versus non-diabetic patients  for objective evaluation of dry eye following phacoemulsification.

This study gained the approval of the Institutional Review Board (IRB) in Faculty of Medicine, Sohag University, Egypt. Our study was designed as a observational comparative   prospective interventional study.  All surgeries were performed in ophthalmology department at sohag university hospital, sohag, Egypt between January 2023 and December 2023. The study is adhered to the tenets of the Declaration of Helsinki.

This study included 60 eyes of 60 patients with visually significant senile cataract. The study eyes were divided into two groups; group A (non- diabetic group) included 30 eyes of 30 patients ,  while  group  B  (diabetic  group) included  30  eyes

 All patient underwent ophathlmological evaluation and Anterior segment imaging  was done using the Avanti RTVue-XR platform (Optovue, Fremont, CA, USA) spectral domain OCT with the add-on lens of the corneal adaptor module (CAM-L mode: S/N 43386). .  these parameters were measured

• Tear Meniscus Height (TMH), Tear Meniscus Depth (TMD), Tear Meniscus Area (TMA)
• all patient were examined preoperative, one month postoperaive and three months postoperative after un uneventual phacoemuslification.

The preoperative results in group A: mean TMH=(348±147μm),mean  TMD=(271±88µm) and mean TMA = 0.087mm²

The preoperative results in group B: mean TMH=302±174μm), mean TMD=(225 ±102µm) and mean  TMA = 0.065mm^2, P ( 0.02)

The tear meniscus height  are affected after one month and regained some improvement after 3 months postoperative in both groups ((212±188μm), (163±202μm) after one month in group A and group B respectively and (279±158μm), (182±163 μm) after three months in group A and group B respectively  P = (0.0001).

 Diabetic patient are more susceptible to dry eye syndrome,  and it becomes more significant and objectively evaluated after phacoemulsification Using tear film meniscus evaluation.
