What is the meaning of capsulotomy?
[ kăp′sə-lŏt′ə-mē ] n. Incision into a capsule, especially that of the crystalline lens of the eye, as to remove cataracts.
What is capsulotomy in cataract surgery?
What Is It? Posterior capsulotomy is a surgical procedure which is sometimes necessary after cataract surgery. Cataract surgery is performed when the lens of the eye, which focuses light rays, becomes cloudy. When it interferes with vision, it is called a cataract and the treatment is to remove the cloudy lens.
What is the function of capsulorhexis?
The capsulorhexis forceps and phaco chopper are used together to rotate the nucleus halves. The capsulorhexis forceps is positioned at the center of lens, the phaco chopper is slid under the capsule again and pulled towards the center.
Why is capsulotomy performed?
YAG laser capsulotomy is surgery to help you see clearly after cataract surgery. You may need this surgery because months or years after cataract surgery, your vision may get fuzzy again. This happens when a membrane in your eye, called the posterior capsule, becomes cloudy.
What is the difference between capsulotomy and Capsulectomy?
During a capsulectomy, a surgeon removes all or part of your capsule from your breast and replaces your implant. During capsulotomy surgery, the capsule is partially removed or released.
Is posterior capsulotomy safe?
NdYAG capsulotomy is generally a safe and successful method in relieving the symptoms of posterior capsular opacification. Documented complications include, transient rise in intraocular pressure,2 retinal detachment,3 lens subluxation or dislocation,4 lens pitting,5 and exacerbation of local endophthalmitis.
Does cataract surgery always involve lens replacement?
During cataract surgery, the clouded lens is removed, and a clear artificial lens is usually implanted. In some cases, however, a cataract may be removed without implanting an artificial lens.
What is an anterior vitrectomy?
The goals of anterior vitrectomy are to remove the vitreous from the anterior chamber, to clear any vitreous from the entry incisions and to allow an IOL to be placed. The bottle height should be greatly lowered, to 15 to 20 centimeters above the eye, before placing the infusion into the anterior chamber.
Is there a more precise way to perform a capsulotomy?
However, on the horizon, there are a number of new approaches that make the capsulotomy more accurate and precise. Box 1. Couching Stabilize the eye with your thumb; introduce the needle perpendicularly into the eye, entering three millimeters behind the limbus. Gradually push forward with a rotating movement.
What are the possible complications of can opener capsulotomy (CCC)?
Complications Like in can opener capsulotomy, anterior capsular radial tears can occur with CCC, if the CCC margin is stretched too much and the reported rates of anterior capsular tears range from 0.5% to 5.6%.[27]
How is anterior capsulotomy used to treat pediatric cataracts?
Vitrectorhexis – Anterior capsulotomy using a vitreous cutter is another widely used technique for anterior capsulotomy in pediatric cataracts and has been reported to be superior to conventional CCC in some studies.[80]
What is the optimal size of capsulotomy for posterior polar cataracts?
Although a 5.5-mm capsulorhexis may be the perfect size of the capsulotomy, different conditions may warrant different sizes. For dense cataracts, a larger capsulorhexis is preferable for safer intraoperative outcomes as opposed to slightly smaller capsulorhexis in posterior polar cataracts to aim for potential placement of IOL in sulcus.[26]
