capsulotomy

 [kap″su-lot´ah-me]
incision of a capsule, as that of the lens, the kidney, or a joint.

cap·su·lot·o·my

(kap'sū-lot'ō-mē),
1. Division of a capsule, as around a breast implant or through scar tissue that might form around a foreign body.
2. Creation of an opening through a capsule; frequently done to gain entry into a joint.
3. Incision of the capsule of the lens in the extracapsular cataract operation.
[L. capsula, capsule, + G. tomē, a cutting]

capsulotomy

(kăp′sə-lŏt′ə-mē)
n.
Incision into a capsule, especially that of the crystalline lens of the eye, as to remove cataracts by surgery.
Breast surgery Closed capsulotomy The manual release of the capsule—the patient’s own scar tissue—around a breast implant
Neurosurgery Anterior capsulotomy A form of psychosurgery in which the presumed fronto-thalamic connections of the anterior limb of the internal capsule of the brain are interrupted—by thermocoagulation using a bipolar electrode system—at the point where the connections pass between the head of the caudate nucleus and putamen
Indications Obsessive neurosis—i.e., OCD—depression
Complications Transient confusion, nocturnal incontinence, seizures, depression, excess fatigue, poor memory, slovenliness
Ophthalmology The opening the lens capsule posteriorly
Orthopaedics An incision into the capsule of a ball joint—femur, humerus—to relieve pressure and decrease the risk of hematomas and bone necrosis

capsulotomy

Cutting a CAPSULE, especially the capsule of the internal lens of the eye.

capsulotomy 

Incision of the capsule of the crystalline lens. Capsulotomy of the anterior capsule is performed in extracapsular cataract extraction (anterior capsulotomy) to enable removal of opaque lens material. The cuts are made with a cystotome along the periphery of the lens in a circular, jagged configuration (called 'can-opener' capsulotomy). It is also performed on the posterior capsule (posterior capsulotomy) when it has become opaque following extracapsular extraction (manual or phacoemulsification) in order to regain the loss of visual acuity. The most common instrument used in this operation is the neodymium-yag laser. See after-cataract; crystalline lens capsule; capsulorhexis; extracapsular cataract extraction.

Twelve (63.2%) of the eyes developed posterior capsule opacification and underwent Nd:YAG laser capsulotomy. Payne et al.
Nd:YAG laser posterior capsulotomy introduced a technique for closed-eye, effective and relatively safe opening of the opacified posterior capsule, and laser capsulotomy rapidly became the standard of care.
After capsulotomy and femoral neck osteotomy, all arthroplasty components were removed, noticing an anterosuperior wall defect in the acetabulum.

Whitman and Vanderveen suggest that older children with simple PCO can undertake laser capsulotomy and those with both PCO and VAO can proceed to surgery [42].
Cataract surgery requires sufficient mydriasis, to facilitate capsulorhexis or capsulotomy, phacoemulsification, and finally intraocular lens insertion.
Objective: To perform a meta-analysis on the precision and safety of femtosecond laser-assisted anterior capsulotomy versus conventional manual continuous curvilinear capsulorrhexis.
