Anterior Chamber Iris Claw Lens for the Treatment of Aphakia in a Patient with Megalocornea
نویسندگان
چکیده
Megalocornea in isolation is a rare congenital enlargement of the cornea greater than 13 mm in diameter. Patients with megalocornea are prone to cataract formation, crystalline lens subluxation, zonular deficiencies and dislocation of the posterior chamber intraocular lens (PCIOL) within the capsular bag. A 55-year-old male with megalocornea in isolation developed subluxation of the capsular bag and PCIOL. The PCIOL and capsular bag were explanted, and the patient was subsequently implanted with an anterior chamber iris claw lens. An anterior chamber iris claw lens is an effective option for the correction of aphakia in patients with megalocornea.

Surgical Management of a Patient with Anterior Megalophthalmos, Lens Subluxation, and a High Risk of Retinal Detachment
The early development of lens opacities and lens subluxation are the most common causes of vision loss in patients with anterior megalophthalmos (AM). Cataract surgery in such patients is challenging, however, because of anatomical abnormalities. Intraocular lens dislocation is the most common postoperative complication. Patients with AM also seem to be affected by a type of vitreoretinopathy t...
متن کاملImplantation of iris-claw Artisan intraocular lens for aphakia in Fuchs’ heterochromic iridocyclitis
Implantation of iris-claw Artisan intraocular lens (IOL) is a surgical option for correction of aphakia; however, these IOLs have not been used in eyes with uveitis including Fuchs' heterochromic iridocyclitis (FHI) due to possible risk of severe postoperative intraocular inflammation. In the case reported here, we secondarily implanted an Artisan IOL in a 28-year-old man with FHI who had aphak...
متن کاملLens implant selection with absence of capsular support.
If contact lens or spectacle correction is not viable, little debate exists that the secondary placement of an intra-ocular lens (IOL) is the method of choice in the absence of capsular support. The choice of IOL mainly depends on the preoperative status of the eye (eg, aphakia in children) and the selected location for the implant. Theoretically, there are several IOL implantation approaches i...
متن کاملRetropupilar positioning of foldable iris-claw intraocular lens for correction of aphakia with no capsular support
SUMMARY Iris-claw intraocular lens (ICIOL) for aphakia needs a large 5.4 mm corneal incision for its implantation. The technique needs corneal suture, associated with some postoperative astigmatism. Foldable ICIOL is used in phakic patients undergoing refractive surgery and has the advantage of a sutureless small corneal incision. We report a case of a high myopic patient with dislocated intrao...
