What is the surgical removal of part of the tissue of the iris called?

What is the difference between iridotomy and iridectomy?
Iridectomy, is a procedure to remove a part of the iris, which is the colored circular membrane behind the cornea of the eye. Earlier this was performed surgically (surgical iridectomy). However, now the procedure is in most cases performed with a laser (laser iridotomy).
What is iris surgery?

Initially developed to treat people with iris defects such as ocular albinism or aniridia. Worldwide, the surgery is sometimes also used cosmetically.What is an iridotomy procedure?
Laser iridotomy, also called laser peripheral iridotomy (LPI), is a method by which ophthalmologists create a microscopic hole in the iris using a laser to open the angle (or internal drainage system of the eye) in patients with narrow or closed angles.
What is the process of enucleation?
In an enucleation, the extraocular muscles are detached from the sclera and then attached to the implant. The tissues surrounding the eye – the tenon’s capsule and conjunctiva – are then closed over the implant. Both surgeries result in the same external appearance.

Listen to pronunciation. (ee-NOO-klee-AY-shun) In medicine, the removal of an organ or tumor in such a way that it comes out clean and whole, like a nut from its shell.
Can an iris be fixed?
Iris surgeries come in the form of iris repair (iridoplasty) or an iris prosthesis. Iris repair often involves the use of sutures inside the eye to reshape the iris to its original shape, re-creating a round pupil. Sometimes the surgeon may cut some of the existing iris to help improve the appearance.Can iris be replaced?
If adequate tissue is present, the iris and pupil can be surgically reconstructed with sutures. In cases where there is excessive loss of issue due to trauma, the Human Optics ArtificialIris (Customflex) may be used to recreate the iris and pupil.
What does the iris do?The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger (dilated) or smaller (constricted).
Article first time published onWhat is the difference between iridotomy and Iridoplasty?
Currently, opinion is that laser peripheral iridotomy (LPI) alone is not sufficient to prevent disease progression. Laser peripheral iridoplasty (LPIP) is an alternative and effective way of widening the angle recess in eyes that are affected by primary angle closure (PAC).
What is a laser iridotomy?
Laser iridotomy is a procedure to treat narrow angles, chronic angle-closure glaucoma, and acute angle-closure glaucoma. The impact of an acute-angle closure glaucoma attack is profound and irreversible, and the condition must be treated immediately.
Is laser iridotomy really necessary?
It is recommended in eyes which have the angle closed for at least half the eye and have high eye pressure or glaucoma. In eyes which have a closed angle but normal eye pressure and no optic nerve damage, laser iridotomy may be recommended as a preventive treatment.
Is iridotomy painful?
The laser peripheral iridotomy is an almost painless procedure. The patient may feel a slight stinging in the eye after the procedure, or a slight foreign body sensation which will go away soon.

What is enucleation and curettage?
Enucleation means completely separating the lesion from the adjacent bone and removing it. Curettage involves raking out the lesion together with part of the adjacent bone (generally, 1-2 mm) using mechanical, physical, and chemical materials.
Why is enucleation done?
Ultimately, the aims of enucleation are to remove diseased tissue, improve patient comfort, replace orbital volume, and give a good functional and cosmetic result for the patient.
What is extended enucleation?
To achieve this end, it sometimes entails the removal of an additional and adequate length of the optic nerve, excision of any adherent conjunctiva and tenon’s fascia to the underlying tumor, or sacrificing a part of the orbital tissue, and this is termed as extended enucleation.
Why is vitrectomy performed?
Vitrectomy procedures are often done to allow surgeons access to the back of the eye, during operations for retinal conditions. It is also commonly done to drain vitreous fluid that has become cloudy or bloody, or filled with floaters or clumps of tissue.
