Description

Ophthalmic surgical instrument

Technical Field

The invention relates to the technical field of medical instruments, in particular to an ophthalmic surgical instrument.

Background

The adhesion between the lens and the vitreous body is gradually deteriorated with the increasing age, so that they are easily separated at the time of the senile cataract surgery, there is no blood vessel in the vitreous body, the required nutrients are derived from the aqueous humor and the choroid, thus the metabolism is slow, and they cannot be regenerated, if there is a defect, the space is filled with the aqueous humor, when the vitreous body is turbid due to various reasons, and when it looks at things, it is felt that mosquitoes fly in front of the eye, and further, with the increasing age, or due to high myopia, the semisolid gel-like vitreous body is gradually changed into a liquid state, which is called vitreous body liquefaction.

The vitrectomy is a high and new technology which develops rapidly in the last decades, solves many incurable diseases of ophthalmology, and is a breakthrough in ophthalmology treatment, the vitreum is a transparent colloid with 99% of water and four fifths of the volume of an eyeball, and the excision by an operation does not cause adverse effect on the eyes of a patient, so that the patient does not have any abnormal feeling.
