Problems solved by technology

[0009] It is not difficult to see from the above analysis that the abnormal proliferation and migration of LEC in the occurrence of PCO is a concentrated expression of the joint action of multiple factors, and it is difficult to achieve effective regulation by interfering with a single link that affects cell function or the external environment of cell survival

Embodiment Construction

[0027] The mechanism of the endogenous electric field is similar to the transmembrane potential generated by the unbalanced flow of ions inside and outside the cell membrane. Due to the polar distribution of sodium and potassium ions on the cell surface and basal side, there is an ion flow in epithelial tissue, which generates a transepithelial potential. When there is a defect in the epithelium or the resistance of the tight junction between cells decreases, the transepithelial potential can drive the current to flow out, and generate a lateral electric field around the above-mentioned part that adapts to its resistance, and affects the cell shape, movement and damage repair.

[0028] 1. Cell migration. Cell migration is the movement of cells after receiving migration signals or feeling the concentration gradient of certain substances, and is an important link in maintaining tissue generation and ensuring self-damage repair. Through the observation of cell migration under ch...

Abstract

The invention relates to eye pads for treating after cataract. Each pad comprises an external power supply, an anode unit and a cathode unit, wherein the anode unit is connected with an anode of the external power supply, and the cathode unit is connected with a cathode of the external power supply and surrounded at the anode unit. The invention provides the eye pads which have obvious curative effect, safe use and no toxic and side effect and can be used for treating after cataract.

Description

technical field [0001] The invention belongs to the field of medical devices, and relates to an eye patch, in particular to an eye patch for treating post-cataract. Background technique [0002] Posterior capsule opacification (PCO) is the main reason that affects the long-term visual recovery after cataract surgery. It occurs due to abnormal ectopic proliferation and migration of lens epithelial cells (LEC) after surgery. [0003] Cataract is currently the world's first blinding eye disease, which not only seriously affects the quality of life of patients, but also occupies an important part of medical resources. Currently, surgery remains the only effective treatment for cataracts. Modern extracapsular cataract extraction or phacoemulsification combined with posterior chamber intraocular lens implantation is the preferred method for cataract vision recovery, and the surgical skills are becoming more and more perfect. It is estimated that by 2020, the annual number of cat...
