Synonym(s): Intracapsular lens extraction (ICLE

Contributor(s): David Gould, David L Williams

Introduction

  • Lendectomy, also known as intracapsular lens extraction (ICLE), is the term used for removal of the lens and its capsule via a large perilimbal corneal incision. The technique is used for the treatment of anterior lens luxation, and in some cases prophylactically for the treatment of lens subluxation (the condition immediately preceding lens luxation, where the lens remainsin situbut becomes increasingly unstable).
  • In dogs, lens luxation Lens: luxation is usually hereditary and bilateral. There is a strong breed predisposition in the Lancashire heeler and terrier breeds. It is also seen in the border collie.

Uses

  • To remove an anteriorly luxated lens, and in some cases prophylactically to remove a subluxated lens.
    Not recommended for the treatment of posterior lens luxation due to the high risk of retinal detachment Retina: detachment.

Advantages

  • Surgical removal of an anteriorly luxated lens is the only treatment available that may successfully restore vision and prevent secondary complications such as glaucoma Glaucoma: due to lens luxation and blindness Blindness.

Disadvantages

  • Difficult surgical technique: magnification, correct microsurgical instrumentation and microsurgical experience are essential.
    Referral to a specialist ophthalmologist is recommended.
  • Post-operative complications may be severe, including wound breakdown, corneal ulceration Ulcerative keratitis , bacterial infection, anterior uveitis Uveitis , secondary glaucoma, retinal detachment Retina: detachment , blindness.
  • Even in surgically successful cases, post-operative vision is reduced due to hyperopia (long-sightedness) caused by the absence of a lens.
  • In dogs, the condition is usually bilateral, so monitoring and/or surgery of the contralateral eye may be required.
