Follow these general tips as you prepare for the surgery: If you take prostate medication such as Flomax, tell your doctor since these alpha-blockers interfere with iris muscles during cataract surgery. PLL results from a single base change mutation in the gene ADAMST17 (ADAMTS17 :c.1473+1). (1995). Hereditary or primary lens luxation: Inherited weakness or degeneration of the lens zonules; Most commonly occurs in terrier breeds of dogs; Typically affects between 3-6 years of age. Reducing PLL with Genetic Testing Now owners of certain breeds Australian Cattle Dog, Chinese Crested, Jack Russell Terrier, Lancashire Heeler, Miniature Bull Terrier, Parson Russell Terrier, Rat Terrier, Sealyham Terrier, Tibetan Terrier, and Welsh Terrier can order a DNA test kit through the Orthopedic Foundation for Animals Web site at www.offa.org. 2014).

Even if frank phacodonesis is not apparent immediately after the trauma, such patients are at higher risk of sub-sequently developing progressive zonular dehiscence. Ultrasound B scan or, occasionally, ultrasound biomicroscopy may be useful for locating a lens posteriorly dislocated behind the iris around the vitreous base. However, damage to the zonular- capsular complex from trauma or disease can lead to structural weakness and loss of lens stability. A small incision will be made in the eye in order to remove the dislocated lens. Many of the complications associated with ACIOLs can be avoided with use of retropupillary placement. With primary lens luxation, both eyes are at risk for dislocation of the lens. Endothelial cell count and central cornea thickness measurement are useful for monitoring corneal health. They will also provide pre-surgery instructions to ensure youre ready on the day of surgery. Lens luxation is a serious, blinding and painful condition. Couching is the earliest known form of cataract surgery, described in people as early as 1700 BC, but still performed in various parts of the world (Omoti 2005). This is extremely painful and can cause permanent blindness. Lakeland Terrier, Lancashire Heeler These zonules anchor the lens capsule to the ciliary body, which is responsible for accommodation or focusing of the lens. Blood tests and other laboratory tests may be ordered to rule out other conditions that may be causing the symptoms. Many recovering patients report clear vision within a few days after the surgery. However, the ophthalmologist should perform regular clinical follow-up and remain vigilant for possible sequelae that might indicate a need for surgical intervention. Movement of the lens can directly inflame the iris and choroid, and aqueous humor dynamics are altered by lens instability. Dilated posterior segment examination with scleral depression, including assessment of the lens capsule, vitreous, and retina, is essential. Pathologic axial myopia is another important underlying etiology associated with acquired lens dislocation. The eye may also be slightly reddened. Give a pet the home they deserve. We provide affordable and accessible animal care resources to families in underserved communities. The surgery to repair posterior luxation is technically very demanding and the risk of complication greater. However, notable differences include the intention for surgery and expectations afterwards. Depending on the severity of lens subluxation, surgery may be performed routinely, or may require the intraoperative insertion of a capsular tension ring, which provides 360 degree outward pressure from within the lens capsule, stabilizing the lens (see video). Primary lens luxation is seen most commonly in middle-aged terrier breeds, and may also occur in other breeds such as the Shar Pei, Border Collie, Lancashire Heeler, and Italian Spitz. In that report, vision was maintained for 1 year in 16 of 20 (80%) eyes and for 2 years in 11 of 19 (58%) of eyes. A thorough systemic examination is helpful in identifying characteristic features suggestive of connective tissue diseases, for example, the tall, lean habitus, hyperflexible joints, and cardiovascular anomalies associated with Marfan syndrome. These will go away as you heal. However, unlike RLE, cataract surgery is considered medically necessary and is covered by most insurance programs, including Medicare and Medicaid. A slitbeam from a transilluminator can illuminate both structures well. Tests are ordered online through the secure area of the OFA website. Dogs suffering from primary lens luxation: these patients are born with a genetic defect that results in a breakdown of the lens zonules - which usually occurs at a young age. These will help ease discomfort and help you relax. Until surgery can be done, pain control is important, as well as control of any glaucoma signs. The mutated gene causes changes even before luxation has occurred. The lens is suspended inside the eye by small fibers called zonules. 5 When you have cataracts, your clear eye lens hardens and appears cloudy. Ideally, posterior vitreous detachment is induced (if not already present) and completed before the lens is manipulated to minimize unintended vitreoretinal traction. Microphakia associated with lens luxation in the cat. J Am Anim Hosp Assoc 31(3): 209-212. In a patient with posterior lens dislocation, clinical evaluation and investigation should be directed at identifying the underlying etiology, evaluating the need for surgical intervention, and planning for surgical or optical rehabilitation. In patients who have complications or bothersome symptoms, the typical approach involves pars plana vitrectomy (PPV) and removal of the dislocated lens, followed by secondary IOL implantation. When this occurs, it's usually best to remove the loose lens before it luxates, thus averting a crisis that requires emergency surgery. 2003;29(3):498-503. This complication can be difficult to successfully treat. They may need to continue using prescription glasses even after surgery. Secondary luxation occurs concurrently with other eye disorders that cause zonule breakage. The patient may experience posture-dependent visual fluctuation, ocular pain, or headache from intermittent angle closure or intraocular inflammation preceding the occurrence of lenticular dislocation into the vitreous cavity. More Info, 350 South Huntington Avenue, Boston, MA 02130 50-52 An abnormality of the lens zonule is believed to lead to a progressive breakdown of the zonular fibers, resulting in subluxation . Lens luxation typically occurs between 3-6 years of age. She also has an interest in Eastern medicine practices and learning about integrative medicine. Although some cases of lens luxation are caused by trauma, severe cataracts or other conditions, most cases are hereditary. The choice of techniques is highly dependent on patient, ocular, and surgeon factors. The eye lens is the clear part of the eye that focuses light and images on the retina. In non-glaucomatous anterior lens luxation (which is common in cats) the initial discomfort and inflammation can often be managed with topical anti-inflammatories and oral pain control (e.g. Through her writing, Dr. Huang enjoys educating patients on how to lead healthier and happier lives. The recovery process may vary from patient to patient. Most people experience clearer vision immediately after surgery. A lens that drifts backward (posteriorly luxated) can also block the drainage angle because of the vitreous that may be displaced forward. Although you might have thought this structure to be found in the knee, it is actually the depression in the anterior face of the vitreous, that itself is formed by the posterior convexity of the lens. Vision Center is funded by our readers. 1 Drolsum L. J Cataract Refract Surg. The surgical removal of a luxated lens is an operation that should only be carried out by an Ophthalmic Specialist due to the special training and skills required to perform the procedure. Primary Lens Luxation (PLL) is a painful inherited eye disorder where the lens of the eye moves from its normal position causing inflammation and glaucoma. In all cases, a thorough eye exam by your veterinarian or a veterinary ophthalmologist is required, with careful evaluation for uveitis and glaucoma. However, these posterior chamber techniques are more surgically challenging and time-consuming, and are generally less stable, than ACIOL implantation.

Possible post-surgical complications include blindness, ongoing glaucoma, eye bleeding, or detachment of the retina. The crystalline lens is normally held in a stable intraocular position by zonular fibers that connect to the ciliary body and attach circumferentially to the equatorial region of the lens capsule. Lens replacement is more difficult in these dogs compared to dogs with cataract surgery because in the latter the entire lens isn't removed. A modified ab externo approach for suture fixation of an intraocular lens implant in the dog. Veterinary Ophthalmology 11(1): 43-48. PLL occurs when the lens spontaneously detaches from its normal residence within the pupil, leading to reduced visual acuity. As long as glaucoma does not occur and there are no symptoms of pain, anterior luxation can even be medically managed longterm (Figure 6). In contrast, posterior dislocation usually involves comanagement with a vitreoretinal surgeon for consideration of vitrectomy and removal of the dislocated lens or IOL through a pars plana approach.
