We are taught-though it is impossible to establish on what authority-that the human crystalline lens specifically protects the retina and choroid from thermal damage. To be more precise: if a glass blower has had a lens removed because of a radiation cataract he is advised not to return to his job. It seems, however, that, if his vision can be restored to enable him to resolve all the necessary...

Tesicon, one of the commercially available 'silicone rubber' lenses, was used in the correction of aphakic patients. In 74% of cases the lenses were considered successful for a daily wear regimen by the patient. Furthermore, a small number of patients could wear this lens without interruption for 3 to 6 days at a time. Despite this good acceptance by patients, corneal problems (mainly staining)...

We prospectively studied for three years the optical correction by contact lenses of 83 aphakic infants (141 eyes) who generally also had systemic and other ocular anomalies: 85% of the patients tolerated the lens wear for the whole study period. Complications occurred in 46 eyes and led to cessation of lens wear in two cases. Ten patients abandoned the lenses for other reasons. Thirty-four eye...

We describe a new surgical technique for treating traumatic aniridia with aphakia and its results in a small consecutive case series. We attached a 3-piece acrylic intraocular lens through the haptics to a customized silicone iris prosthesis. The combined implant was inserted through a 5-mm incision and fixated with a transscleral suture in the ciliary sulcus using a knotless technique (Z sutur...

Abstract In the present cases, use of Ophtec Arificial Iris model C1 is described in patients with traumatic or postoperative aniridia/aphakia. one patients, it was combined perforating keratoplasty because corneal scarring. both presented improvement visual acuity and a satisfactory aesthetic result without any serious complications can be shown. However, short follow-up time must emphasised.

AIM To assess clinical variables and vitreous protein as risk factors for the development of postoperative proliferative vitreoretinopathy (PVR). METHODS A prospective study was conducted on 140 patients with a rhegmatogenous retinal detachment in whom a primary vitrectomy was performed. 12 clinical variables were recorded and vitreous samples obtained for measurement of protein concentration...

Cataract surgery is the most frequently performed surgical procedure worldwide. We aim to determine the prevalence of having implanted an artificial lens (pseudophakia) and of no lens (aphakia) and to compare visual function.As part of the Gutenberg Health study, a population-based cross-sectional study was conducted in Germany. An ophthalmological examination including slit-lamp examination wa...

PURPOSE We present the first in vivo CT and MR imaging description of intraocular lenses (IOLs), which are commonly encountered in elderly patients who have undergone cataract surgery. METHODS A retrospective review was done of the imaging studies of 20 patients (22 eyes) with IOLs and of three patients (four eyes) with aphakia. CT and MR studies were performed with standard clinical protocol...
