FOXE3 is a forkhead- box transcription factor which is involved in the proper formation of the ocular lens and is post-natally expressed in the lens epithelium.

On 1 June 2014, his vision was restored by a "glued intra ocular lens" technique. He was also performing on the stage 50 meters away at the Congress rally in Sriperumbudur on 21 May 1991, when a human bomb killed Rajiv Gandhi.

The eyepiece, or ocular lens, is a cylinder containing two or more lenses; its function is to bring the image into focus for the eye. The eyepiece is inserted into the top end of the body tube. Eyepieces are interchangeable and many different eyepieces can be inserted with different degrees of magnification. Typical magnification values for eyepieces include 5×, 10× (the most common), 15× and 20×.

In early 2002, changes occurred in the teaching of basic medicine. Centers for teaching medical students in pediatric surgery, sports medicine, neonatal, and the Department of Clinical Biochemistry became separate clinics. Over the years the hospital has undergone thorough modernization including a new surgical department completed in 2011. In September 2012 the Clinic of Ophthalmology performed Slovakia's first intra-ocular lens implantation, curing two patients with cataracts.

A collection of different types of eyepieces. An eyepiece, or ocular lens, is a type of lens that is attached to a variety of optical devices such as telescopes and microscopes. It is so named because it is usually the lens that is closest to the eye when someone looks through the device. The objective lens or mirror collects light and brings it to focus creating an image.

Glassblowers tend to work with very high- temperature objects and equipment, which emit a great deal of infrared radiation through black-body radiation. The ocular lens, like all matter, has the capacity to store incident photon energy by resonance absorption. Absorption of infrared photons increases vibration of molecules, which is observed as increased temperature. Large important biomolecules such as proteins tend to lose their space structure when vibrating, known as denaturation.

Dr. Helena Ndaipovanhu Ndume () is a Namibian ophthalmologist, notable for her charitable work among sufferers of eye-related illnesses in Namibia. To date, Dr. Ndume has ensured that some 30,000 blind Namibians have received eye surgery and are fitted with intra-ocular lens implants free of charge. She is currently the head of the Ophthalmology department at Windhoek Central Hospital, Namibia’s largest hospital, and is one of only six Namibian ophthalmologists. She was listed as one of BBC's 100 women during 2018.

BFSP2 is a gene that encodes the protein phakinin ("beaded filament structural protein 2") in humans. More than 99% of the vertebrate ocular lens consists of terminally differentiated lens fiber cells. Two lens-specific intermediate filament proteins, the protein product of this gene (CP49 or phakinin) and filensin (also known as CP115), are expressed only after fiber cell differentiation has begun. Both proteins are found in a structurally unique cytoskeletal element that is referred to as the beaded filament (BF).

9,10 Here 2 scleral flaps about 180 degrees apart are made and the IOL is inserted through the corneal incision (Fig 3). After making the sclerotomy below the flaps, the haptics are externalized and tucked in a scleral tunnel at the point of exit. Maggi and Maggi in 1997 were the first to report sutureless scleral fixation of a special IOL. Gabor Scharioth and Pavilidis in 2006 reported the scleral tuck and intrascleral haptic fixation of a posterior chamber Intra ocular lens (PC IOL).

Major intrinsic protein is a member of the water- transporting aquaporins as well as the original member of the MIP family of channel proteins. The function of the fiber cell membrane protein encoded by this gene is undetermined, yet this protein is speculated to play a role in intracellular communication. The MIP protein is expressed in the ocular lens and is required for correct lens function. This gene has been mapped among aquaporins AQP2, AQP5, and AQP6, in a potential gene cluster at 12q13.

The telescope: overall side view (top); the siderostat (left) and lens tube (right); ocular lens end (inset) The telescope had two interchangeable objective lenses (for visual and photographic use respectively) in diameter, with a focal length of . Due to its extremely large size, the telescope was mounted in a fixed horizontal position. Light from astronomical objects was redirected into the optical tube assembly via a Foucault siderostat, a movable plane mirror in diameter, mounted in a large cast-iron frame at the objective lens end of the telescope. The horizontal steel tube was long. The telescope’s eyepiece/plate end could be shifted five feet on rails for focusing.
