Vitrectomy is to remove the turbid vitreous body or remove the traction of vitreous retina, restore transparent refractive stroma and promote retinal reset, treat vitreoretinal diseases and restore the visual function of patients.
The indications of vitrectomy are expanding day by day, and the scope of operation covers almost all parts of the eyeball except cornea and sclera. Specifically, its indications are divided into anterior segment and posterior segment.
Vitrectomy, as a high-precision ophthalmic operation, has obvious advantages. Specifically, vitrectomy has the following advantages:
1. Vitrectomy is performed under local anesthesia, which has the advantages of less trauma, high safety and wide surgical indications.
2. With the progress of society and the aggravation of aging process, age-related macular degeneration is increasing day by day, at the same time, there are more and more myopia and diabetes patients, and vitreoretinal diseases are also increasing. Vitrectomy can greatly improve the symptoms of these patients and avoid more blindness or eyeball atrophy.
3. By removing turbid or organized vitreous body, pus and hematocele, bacteria and toxins can be removed, and the transparency of refractive stroma in vitreous cavity can be restored;
4. Take out the foreign body accurately under direct vision, avoid blindness, and minimize the damage to surrounding tissues;
5. It can improve the extraction rate of foreign bodies in vitreous cavity, and can simultaneously extract multiple or multiple foreign bodies, especially nonmagnetic foreign bodies, encapsulated foreign bodies, impacted foreign bodies in retina, etc.
6. Vitreous lesions can be obtained directly and accurately, and the positive rate of pathogenic examination can be improved;
7. Traumatic cataract, retinal detachment, retinal tear, silicone oil filling and other operations can be performed at the same time, which reduces the number of operations, avoids the damage to the intraocular structure of the affected eye caused by multiple operations, reduces the hospitalization expenses of patients, and restores the visual function of the affected eye to the maximum extent.
Vitrectomy is a high-level modern microsurgery, which is difficult, long in operation time, expensive in equipment, high in technology and high in requirements for surgeons. It has gradually become the embodiment of a hospital's technical level and comprehensive strength.
