A lens implant is a small, plastic lens that an eye provider can put in your eye to replace a lens that has been removed because of a cataract. Usually the plastic lens is implanted during surgery to remove the cataract. A secondary lens implant is one that is done in a separate surgery after cataract surgery. The posterior chamber has a lens capsule that holds the lens implant in position. At the conclusion of cataract surgery, the incision is checked for proper closure and eyedrop medications are used postoperatively to prevent infection and facilitate healing.
Purpose. To assess visual results and complications of a modified technique of posterior chamber intraocular lenses (PC IOLs) in aphakic eyes without scleral flaps. Methods. Modified one-haptic scleral fixation was performed in one eye each of 25 patients with aphakia and insufficient capsule support. Follow-up period was six by: 6. The Trulign Toric Posterior Chamber Intraocular Lens is intended for primary implantation in the capsular bag of the eye for th e visual correction of aphakia and YAG-laser posterior capsulotomies should be delayed until at least 12 weeks after the implant surgery.

In , first intraocular lens (IOL) insertion after cataract surgery was performed by Sir Harold Ridley, in London. Only in the s, the IOL insertion after cataract surgery began to be a standard procedure. The material the first IOL-s were composed of was polymethyl methacrylate (PMMA). The PMMA is a rigid material and the corneal incision had to be at least as big as the Author: Samir Čanović, Suzana Konjevoda, Ana Didović Pavičić, Robert Stanić. The patient sustained a large open lacerated wound to the left eye. The posterior chamber was ruptured and significant vitreous and some intraocular tissue was lost. The eyeball was not repairable and was removed, en masse. A permanent implant was inserted but not attached to the extraocular muscles.

New York: Raven Press, © Previous reports of posterior chamber phakic IOL surgery report an incidence of lens opacity from % to 25%. Maeng et al reported that cataract developed in 8 (%) of 26 eyes (6 of 20 patients) a mean of months ± (SD) by: If the capsular bag is not intact at the end of the surgery, a posterior chamber lens may be fixated in the ciliary sulcus, in front of the anterior lens capsule if there is enough capsular support present.
Clinical evidence suggests that IOLs fixated in the sulcus should have a smooth rounded anterior optic edge and thin haptics (Figure 6A). We aimed to evaluate the implantation of a posterior chamber intraocular lens (IOL) in the anterior chamber (AC) with the haptics passing through two iridectomies to the posterior chamber.

Secondary posterior chamber lens implants were performed on sixty-nine patients. Although technically the insertions were slightly more difficult than in a primary case, the results were excellent.

To take the place of the clouded human lens, a precisely engineered artificial lens called the intraocular lens, or “IOL”, is implanted into the eye at the time of cataract a contact lens, it is permanently fixated inside the eye.
Although pseudophakic pupillary block with a posterior chamber lens implant is rare in an otherwise normal eye, the eyes of diabetic patients and those with current or past history of ocular inflammation are at particular risk for this problem.
In these cases, a peripheral surgical iridectomy should be strongly considered at the time of. Journal of Refractive Surgery | ABSTRACTPURPOSE: To examine the efficacy, predictability, stability, and safety of posterior chamber phakic intraocular Cited by: Treatment – Lens Exchange.
Probably the most common procedure done for a dislocated intraocular lens is a lens exchange. The offending IOL is removed from the eye and a new lens is placed in the eye.
If there is some capsule left in the eye that will support a larger IOL then a posterior chamber lens can be placed in the eye. Intraocular lens (IOL) is a lens implanted in the eye as part of a treatment for cataracts or most common type of IOL is the pseudophakic IOL.
These are implanted during cataract surgery, after the cloudy eye's natural lens (colloquially called a cataract) has been removed.
The pseudophakic IOL provides the same light focusing function as the natural ICDCM: Twenty-two (88%) of 25 grafts in the anterior-chamber intraocular lens group and 23 (96%) of 24 grafts in the sutured posterior-chamber intraocular lens group were clear after 1 year; best.

Phakic IOL (intraocular lens), also known as Visian Implantable Collamer Lens or ICL is a rising alternative to LASIK eye surgery and PRK for correcting moderate to severe myopia and can in some cases actually produce superior vision when compared to laser refractive surgery options such as Lasik and Lasek.

The Visian ICL is placed in the posterior chamber of the eye behind the iris and pupil and in front of the natural lens. Once the phakic lens implant has been centered, the doctor fastens it in place and sutures the incision.

However, the posterior chamber IOL (PCIOL)—namely, the capsular-supported PCIOL and, in the absence of capsular support, the iris-sutured or transsclerally sutured PCIOL—offers numerous.

Anterior segment OCT (AS-OCT) is an optical and noncontact imaging technology, which has numerous fields of application in the imaging of the cornea, anterior chamber, and the lens.
In this chapter, we will present some of the application fields of AS-OCT in corneal, cataract, and refractive surgery. We will emphasize the potential of AS-OCT by several clinical examples Cited by: 1.Therefore, an IOL exchange is an appealing method of restoring vision in a patient with a dislocated posterior chamber IOL because the same procedure can work in most situations.
