Ophthalmic Viscoelastic Devices: Revolutionizing Eye Surgery

Ophthalmic Viscoelastic Devices

Ophthalmic Viscoelastic Devices (OVDs) have transformed the field of ophthalmic surgery, offering improved outcomes and enhanced patient safety. These specialized substances are used during various eye surgeries, including cataract surgery and intraocular lens implantation. OVDs provide crucial support to the delicate ocular tissues, facilitating surgical procedures, protecting the eye, and ensuring optimal visual outcomes. This article delves into the world of ophthalmic viscoelastic devices, exploring their composition, applications, benefits, and contribution to advancements in eye surgery.

Ophthalmic Viscoelastic Devices are gel-like substances used in eye surgery to maintain the anterior chamber's stability and protect ocular tissues. They are injected into the eye during procedures such as cataract surgery, corneal transplantation, and glaucoma surgery. OVDs possess unique physical and chemical properties that allow them to serve as space fillers, protectors, and lubricants within the eye.

 

The Global Ophthalmic Viscoelastic Devices Market Was Valued At US$ 810.9 Million In 2019 And Is Expected To Register A CAGR Of 9.4% During The Forecast Period (2019–2027).

 

OVDs consist of two main components: a viscous polymer and a lubricating agent. The polymer provides the substance with its gel-like consistency, while the lubricating agent ensures smooth intraocular movements. There are two primary types of OVDs:

 

a) Cohesive OVDs: Cohesive OVDs have a high molecular weight and a thicker consistency. They maintain their structure and remain intact within the anterior chamber, creating a stable environment during surgery. Cohesive OVDs are commonly used for capsular bag stabilization during cataract surgery.

 

b) Dispersive OVDs: Dispersive OVDs have a lower molecular weight and a more fluid consistency. They spread over the endothelium and form a protective layer, reducing friction and preventing tissue damage. Dispersive OVDs are often used during procedures involving delicate structures, such as corneal transplantation.

 

OVDs have revolutionized several aspects of ophthalmic surgery, contributing to improved outcomes and patient safety:

a) Cataract Surgery: OVDs are extensively used during cataract surgery to create and maintain space within the anterior chamber. They protect the corneal endothelium, stabilize the capsular bag, and aid in the insertion and positioning of intraocular lenses.

 

b) Corneal Transplantation: OVDs play a vital role in corneal transplantation surgeries. They facilitate the manipulation of the donor cornea, protect the endothelium, and maintain the anterior chamber's stability during graft placement.

 

c) Glaucoma Surgery: OVDs are utilized in glaucoma surgeries, such as trabeculectomy or tube shunt procedures. They help create space, protect delicate tissues, and prevent postoperative scarring.

Treatment For Eosinophilic Esophagitis Includes Both Pharmaceutical Therapy And Dietary Management

Image
  Eosinophilic Esophagitis Since the last 20 years, Eosinophilic Esophagitis (EoE) has been recognised as a chronic, immune- mediated, atopic inflammatory illness of the oesophagus. EoE-related eosinophil infiltration causes chronic discomfort and tissue damage in the oesophagus. It is examined by histologic analysis of one or more esophageal biopsy specimens that have less than 15 eosinophils per high impact field (eos/hpf), preventing the pathological gastrointestinal reflux disease (GERD). The development of eosinophilic esophagitis is caused by a lack of mucosal blockage in the oesophagus and a reverse immunological response that results in fissures/lesions, fibrosis, and dysmotility in the oesophagus, all of which are aided by Th2 interleukins. There is a 7% chance that Eosinophilic Esophagitis will be genetically inherited. Food aversions, exposure to inappropriate antibiotic use, acid reflux, and early signs of gastro-intestinal disorders are other common issues. Treatment for E

Bio-Identical Hormones Are Synthetic Hormones That Mimic Natural Hormones In The Body

Image
Bio-Identical Hormones  Man-made hormones called Bio-identical Hormones are used to treat low or unbalanced hormonal levels. Bioidentical hormones resemble the hormones that are created naturally in both men and women's bodies. The hormonal imbalance and its effects on the body and inside of it are treated with bioidentical hormones. Men typically experience hormone imbalance after the age of 40.The body's hormones are primarily in charge of regulating a variety of processes, including food metabolism and sexual desire. Hormonal levels change throughout time, especially in women who are close to menopause. Hormonal changes in men are visible after age 40. In order to balance oestrogen and progesterone in women, hormone replacement therapy is frequently employed. Bio-identical Hormones are simply synthetic hormones that resemble the hormones the body naturally produces. These hormones are used to treat men's and women's hormonal imbalances or low hormone levels. Testos
