Comparison of Wound Integrity for Clear Corneal Cataract Incisions

Status Completed

Clinical Trial Summary

This is a randomized controlled trial to evaluate the safety and efficacy of two different closing methods for clear corneal cataract incisions

Clinical Trial Description

Compared with other incision types , clear corneal incision has the advantages of simple operation, small incision and good healing. It has been widely used in recent decades and has become the most commonly used incision type in phacoemulsification cataract surgery.However, there is no unified standard for the closed method of the clear corneal incision, and some studies have shown that the wound Integrity of clear corneal incision is not well.In the poorly closed incision, the risk of infection increased due to the leakage .Especially in 2.2mm incision, the frequent entry and exit of the instrument reduces the corneal rebound ability at the incision so that the incision is hard to closed. Ensuring wound Integrity for clear corneal cataract incision is the key to the success of cataract surgery. Clinically closed methods include stromal hydration and suture.The effectiveness of stromal hydration as one of the most commonly used methods has been validated, but also adds additional negative effects. Additionally, the suture extends the operation time and improves the operation cost, and is also accompanied by some complications, which has been less used. Exploring a safe and effective closed method will benefit for most cataract patients. This study intends to evaluate the safety and efficacy of a closed method that incision is pressed by a cotton swab.The investigators planned to select 130 cataract patients who met the inclusion criteria. The investigators will press the clear corneal incision with a cotton swab in experimental group, while the control group used stromal hydration to close the corneal incision. Wound Integrity, wound leakage, corneal thickness at the incision, keratometric value at the incision, anterior chamber depth and incidence of incision-related descemet membrane detachment were compared between the two groups. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
