Description

Tool for ophthalmic surgery supplied with perfusion fluid}

The present invention relates to a tool for ophthalmic surgery in which the perfusate is supplied to adjust the position of an artificial lens lens in the cornea together with the supply of perfusate during ophthalmic surgery.

In general, lens implantation is a type of vision correction surgery in which an artificial lens lens is inserted into the cornea while leaving the lens in the eyeball to correct refractive errors such as myopia.

These lens implantation procedures include anterior lens implantation (iris-supported lens) in which a lens is inserted in front of the iris and fixed to the iris according to the insertion position of the artificial lens, and posterior lens implantation in which the lens is inserted between the rear of the iris and the front of the lens (rear In addition to this, there is a right angle support type lens implantation in which a lens is inserted in front of the iris and inserted into the space where the cornea and the iris meet.

Unlike LASIK and LASEK, which are other methods of vision correction, such lens implantation allows quick and stable vision recovery because it does not damage the corneal tissue, and highly myopia patients who are unable to LASIK and LASEK due to the thin cornea. It can also be applied to.

In addition, since it is a surgical method that preserves the cornea as it is, there is almost no occurrence of dry eye syndrome after surgery, and there is almost no myopic regression, so stable vision can be maintained.

On the other hand, corneal endothelial cells have a barrier function and a pump function to maintain the degree of hydration of the cornea constant to maintain the transparency of the cornea, and are very sensitive and are easily damaged by osmotic pressure change, pH change, and the presence or absence of electrolytes.

Therefore, in the ophthalmic procedure, the use of perfusate is essential to protect corneal endothelial cells while maintaining an anterior positive pressure.

Even if the perfusate is used for less than 30 minutes, it takes up to 4 to 8.5 hours to be replaced by the aqueous solution after surgery, and the importance of the perfusate is great because it can sufficiently damage the corneal endothelial cells.

In addition, it is important to keep the anterior depth as constant as possible to reduce damage due to friction with surrounding tissues such as the corneal endothelium, iris, and posterior lens capsule.

The perfusate plays a role of protecting corneal endothelial cells, such as protecting corneal endothelial cells from acid and base changes during the procedure, maintaining adequate tonicity and electrolyte concentration, and serving as an energy source.

A viscoelastic material may be used instead of the perfusate, wherein the viscoelastic material refers to a mucoelastic material.

However, if the viscoelastic material is adhered to the intraocular tissue after the procedure and cannot be completely removed, the intraocular pressure may increase, resulting in sequelae.

Accordingly, a balanced salt solution that is most similar to water formed in the eye can be used as the perfusate, and the balanced salt solution is sodium chloride 640mg, potassium chloride 75mg, magnesium chloride 30mg, sodium acetate 390mg, sodium citrate 170mg, etc. Can be made.

This equilibrium saline solution purifies the eye tissues, maintains moisture in the eye tissues, protects the lens and corneal endothelium during ophthalmic surgery, and supplies calcium and magnesium necessary to maintain intracellular and intercellular functions.

However, conventionally, in supplying the perfusate during the procedure using a separate perfusate supply device, the number of surgical equipment increases, the operation process becomes complicated, and the time required for recovery becomes delayed as the operation time takes longer. There was a problem of lowering the efficiency.
