Cataract ultrasonic emulsification and folding intraocular lens implantation method

Abstract

The invention belongs to the field of ophthalmologic operations, and discloses a cataract ultrasonic emulsification and intraocular lens implantation method. In a cataract ultrasonic emulsification and intraocular lens implantation operation, a viscoelastic agent is used in two steps of capsulorhexis and folding intraocular lens implantation. In the capsulorhexis step, a capsulorhexis needle and an iris restorer are used and enter the anterior chamber from a main incision and an auxiliary incision respectively for continuous annular capsulorhexis operation, and it is guaranteed that the stability of the anterior chamber can be maintained without using a viscoelastic agent; in the step of implanting the folded intraocular lens, equilibrium liquid is injected from a surgical main incision to fill the anterior chamber and the capsular bag, the head of the intraocular lens implanting device abuts against the main incision to form a closed channel, the folded intraocular lens is implanted into the anterior chamber through the closed incision under the closed condition, and the safety of the step of implanting the intraocular lens is guaranteed under the condition that no viscoelastic agent is used for protection. According to the invention, no viscoelastic agent is used in the whole cataract surgery process, so that the side reaction of the viscoelastic agent to eyes is avoided; and the infection probability increased due to the fact that the instrument repeatedly enters the eyes is reduced.

Description

technical field [0001] The invention belongs to the field of ophthalmic surgery, and in particular relates to a method (or technology) for cataract phacoemulsification and folding artificial lens implantation. Background technique [0002] At present, the existing technology commonly used in the industry is as follows: the traditional operation steps are: making the main incision (3mm) and auxiliary incision (1mm); viscoelastic agent is injected into the anterior chamber to maintain the normal operating space of the anterior chamber, and continuous circular capsulorhexis is performed. Create conditions; the capsulorhexis forceps continuously tear the anterior capsule of the lens; the water under the anterior capsule is separated to fully dissociate the nucleus from the cortex and the capsular bag; the crystal nucleus is phacoemulsified; the residual cortex in the capsular bag is sucked; The operation space of the room and the capsular bag creates conditions for the implantat...

AI Technical Summary

Problems solved by technology

[0004] (1) If the circular capsulorhexis operation does not use viscoelastic agent, the anterior chamber will collapse and cannot be completed, which will cause surgical risks, such as damage to the corneal endothelium, iris, and lens capsule, and even ciliary ring block leading to increased intraocular pressure, etc. , these are the important factors causing the failure of the operation

[0005] (2) When implanting intraocular lens, if no viscoelastic agent is used, the anterior chamber collapse will not only cause the above risks, but also cause the rupture of the posterior capsule and the overflow of the vitreous body, which will cause serious complications, such as detachment of the net, pulse detachment, pulse Blood, infection, etc., so that the intraocular lens cannot be implanted and the operation fails
