What is Lensectomy?

Lensectomy-vitrectomy is the removal of the crystalline lens through a transscleral retrociliary incision (usually the pars plana) under clinical conditions in which the vitreous gel has to be partially or totally removed. It was designed in the early 1970s at the onset of modern vitreous surgery.

What is a pars plana vitrectomy mean?

Pars plana vitrectomy (PPV) is a microsurgical procedure used by retina surgeons to perform a variety of operations. The first step in this procedure is to remove the “vitreous gel” that fills the back of the eye (hence “vitrectomy”).

What is vitrectomy done for?

A vitrectomy is a type of eye surgery to treat various problems with the retina and vitreous. During the surgery, your surgeon removes the vitreous and replaces it with another solution. The vitreous is a gel-like substance that fills the middle portion of your eye.

What is the difference between refractive lens exchange and cataract surgery?

The only difference is that cataract surgery is performed to remove the cloudy eye lens that causes vision to become blurred, while refractive lens exchange is performed with the intention of removing the need to wear glasses or lenses.

What is pars plana Lensectomy?

Pars plana lensectomy, wherein the entire lens within the pupillary area (the anterior capsule, anterior cortex, nucleus, posterior cortex, and posterior capsule) is removed, is now a well-established technique.

Does a vitrectomy improve vision?

Although vitrectomy improves or stabilizes vision in most cases, vision may not be fully normal after the surgery. This is especially true if your condition caused permanent damage to your retina. Vitrectomy is generally a safe procedure.

How quickly do cataracts develop after vitrectomy?

Pars plana vitrectomy (PPV) is a well-recognized risk factor for cataract progression. In almost all cases, a visually significant cataract develops months to years after surgery. Rarely, a cataract develops 1 to 7 days after a vitreous procedure.

Is vitrectomy laser surgery?

Vitrectomy is a surgical procedure undertaken by a specialist where the vitreous humor gel that fills the eye cavity is removed to provide better access to the retina. This allows for a variety of repairs, including the removal of scar tissue, laser repair of retinal detachments and treatment of macular holes.

How painful is a vitrectomy?

You might have some pain in your eye and your vision may be blurry for a few days after the surgery. You will need 2 to 4 weeks to recover before you can do your normal activities again. It may take longer for your vision to get back to normal.

What is the success rate of a vitrectomy?

Patients who underwent pars plana vitrectomy (PPV) had a success rate of 89.6%, patients who underwent scleral buckle (SB) had a success rate of 86.9%, and patients who underwent PPV with SB had a success rate of 89.3%.

What can you not do after a vitrectomy?

Wear the eye shield over the operated eye at night and when sleeping for the first week after vitrectomy surgery. Avoid travelling by flight for a few days post operation.

How long does vitrectomy surgery take?

How long will the vitrectomy take? The length of the vitrectomy depends on the problem you have. Time for surgery can be from 30 minutes to over 3 hours. Your physician will discuss with you the approximate time he anticipates for your surgery.

How long does it take to recover from epiretinal membrane?

The macular pucker surgery recovery time can vary from between three to six months. Healing occurs gradually over this time, with most people regaining about half of the vision lost from a macular pucker.

Can you go blind from epiretinal membrane?

An epiretinal membrane does not make an eye go completely blind. It typically affects only the center area of vision and does not cause a loss of the peripheral (side) vision.

Is epiretinal membrane serious?

ERMs are severe when they affect the central part of the retina responsible for seeing fine details, for example, when reading or recognizing faces. In the severest cases, vision is blurred and distorted, similarly to a distorted view through an unadjusted pair of binoculars.

Should I have surgery for epiretinal membrane?

If your symptoms are significant you may want to consider surgery to help maximize the vision in your affect eye. Surgery is the only way to treat an epiretinal membrane, there are no eye drops or medications that you can take that will help.

Does cataract surgery cause epiretinal membrane?

Results : Following cataract surgery, ERMs remained stable in 36% of eyes and worsened in 64%. In contrast, ERMs were stable in 60% and worsened in 40% of eyes without CE (p < 0.025, Chi-square analysis).

What causes epiretinal membranes?

In the majority of cases, Epiretinal membranes happen as a part of the normal aging process in which changes occur inside the eye. It is common in people who are over the age of 50. The key cause of this condition is the vitreous gel peels away from the retina. It may also form following a retinal or eye surgery.

How successful is epiretinal membrane surgery?

Purpose: Surgery has been successful in removing epiretinal membranes (ERM) from the macula, allowing some improvement in vision in 80-90% of patients; however, complications are relatively frequent.

Can you drive with epiretinal membrane?

An eye patch will cover the healing eye until the next day, and eye drops or ointment will be necessary for several weeks. Post surgery, patients can usually resume normal, non-strenuous physical activities within 24 hours, however driving, returning to work and other visual tasks will vary from person to person.

What causes Metamorphopsia?

[1] suggested that metamorphopsia is not only caused by displacement of retinal layers resulting in mislocation of light on the retina, but also by the combination of retinal changes with cortical processing, mainly after long-standing maculopathy or after treatment of macular disorders (as neovascular AMD).
