What this Trial Is About
Researchers are evaluating the impact of regularly using Systane COMPLETE in patients with mixed dry eye who are planning to undergo cataract surgery. The study aims to see if this treatment can improve the accuracy of predicting residual astigmatism after surgery. Participants are adults aged 20 to 85 years with normal cognitive function who require cataract surgery with intraocular lens implantation. Participants will use Systane COMPLETE eye drops, applying 1 to 2 drops four times daily in both eyes for 1 to 2 months before surgery. The study includes a screening visit 1 to 2 months before surgery where demographic information, preoperative assessments, and dry eye evaluations are performed. Measurements of the cornea will be taken using specialized devices to monitor the ocular surface and detect irregularities. Seven days before surgery, participants will have repeat eye exams and biometry measurements to guide lens selection. On surgery day, participants will undergo cataract surgery with intraocular lens implantation, and medication use will be monitored through returned bottles and diaries. During the study, participants will complete questionnaires such as the OSDI Dry Eye Questionnaire and undergo vision and corneal surface assessments. Measurements include biometry and corneal topography, as well as non-invasive tear break-up time tests. These evaluations will occur at screening and pre-operative visits to track changes in the ocular surface. Compliance with treatment will be checked at surgery. The study will last until the end of 2027, focusing on optimizing the ocular surface to improve surgical outcomes for dry eye patients undergoing cataract surgery.
