Celebrating 25 Years of Optical Biometry: A Milestone in Ophthalmology.

Optical biometry has fundamentally transformed cataract surgery, and 2024 marked 25 years since the introduction of the first optical biometer. In the early 1980 s, Fercher and colleagues pioneered the optical noncontact eye length measurement, leading to the first interferometric A-scan of the eye. This innovation, patented and later developed by Zeiss, culminated in the release of the IOLMaster in 1999, enabling more accurate and reproducible eye diagnostics.

VITAMIN D LEVEL AND ITS LINK WITH VISUAL ACUITY AND CONTRAST SENSITIVITY IN PATIENTS WITH AGE-RELATED MACULAR DEGENERATION.

Objective: The aim: Determination of vitamin D level and its connection with visual functions in patients with age-related macular degeneration, dry form.

Patients And Methods: Materials and methods: We analyzed the data of studies (25(OH)D3 levels (nmol/l), LogMAR visual acuity and Logarithmic contrast sensitivity) of 2 groups of women of postmenopausal age: 1 group (58 people - 58 eyes) - patients with age-related macular degeneration (dry form) - study group; 2 group (29 people - 29 eyes) - people without ophthalmic pathology - control group.

Results: Results: In the study group, 37 patients (63,8%) had vitamin D deficiency, 21 people (36,2%) had vitamin D insufficiency.

The Development and Status of Eye Banking with Special Focus on the Commitment of LIONS Clubs.

Background: Ever since the first successful keratoplasty in 1905, there has been a need to store corneas for transplantation. R. Townley Paton founded the first eye bank in New York in 1944.

[Calculating the Human Eye - The Evolution of Biometry for Cataract Surgery].

Introduction: Optical biometry is the standard diagnostic tool and essential basis for IOL calculation prior to cataract surgery today. Our article will provide a short overview of the historical development of biometry of the human eye and the formulas used for IOL calculation.

Material And Methods: Selective literature search in books and journal articles via PubMed, Google Scholar and Google as well as close cooperation with IOLCon at Saarland University, Homburg/Saar (Germany).

Lights and darks of a picture. The life of Giovanni Francesco Barbieri, "il Guercino" - the squinter.

Purpose: To be cross-eyed is a wide-spread dysfunction of the eye and squinting is currently regarded as unattractive. However, in ancient times, societies saw squinting as a sign of piety or even beauty. Even Venus was depicted heterophoric quite often.

From Reading Stones, Glasses and Contact Lenses to Intraocular Lenses & Ophthalmic Lasers--A Short Overview over the History of Visual Aids.

Alhazen, ibn al-Haytham, (965 Basra - c. 1040 in Cairo) was a Muslim polymath who made significant contributions to the principles of optics, being the first to recognize the optical effect by transparent objects in the 11th century. His insights led to a fundamental revolution, enabling older presbyopic persons to read again.
