CRYOSURGERY IN OPHTHALMOLOGY (CRYOPEXY)

Cryosurgery, also known as cryopexy, is a medical procedure that uses extremely cold temperatures to destroy abnormal tissue in the eye. In ophthalmology, cryosurgery is used to treat a variety of conditions, including retinal detachment, age-related macular degeneration, and certain types of retinoblastoma.

The procedure begins with the application of a special cryoprobe to the affected area of the eye. The cryoprobe is connected to a device that cools it to extremely low temperatures, typically between -20 and -40 degrees Celsius. The cold temperatures cause the abnormal tissue to freeze and die, which can prevent further damage to the eye.

Cryosurgery is typically performed by an ophthalmologist, a medical doctor who specializes in the treatment of eye conditions. The procedure is usually performed on an outpatient basis and takes about 30 minutes to an hour to complete.

Cryosurgery is a relatively safe procedure with low complication rates. Some patients may experience temporary side effects such as pain, redness, or swelling of the eye, but these usually resolve on their own within a few days. In rare cases, more serious complications such as infection or bleeding can occur, but these can be treated with antibiotics or additional surgery.

Cryosurgery can be an effective treatment option for retinal detachment, a condition in which the retina, the light-sensitive layer of tissue at the back of the eye, becomes separated from the underlying layers. It can also be used to treat certain types of age-related macular degeneration, a condition that causes damage to the macula, the central portion of the retina. Cryosurgery is also used to treat retinoblastoma, a rare form of eye cancer that affects children.

It's important to note that Cryosurgery should be done after a comprehensive eye exam by an ophthalmologist, and a clear understanding of the risks and benefits of the procedure should be discussed with the patient before undergoing the procedure.

In conclusion, Cryosurgery, also known as cryopexy, is a medical procedure that uses extremely cold temperatures to destroy abnormal tissue in the eye. It is used to treat a variety of conditions, including retinal detachment, age-related macular degeneration, and certain types of retinoblastoma. It's a relatively safe procedure with low complication rates, but it should be done after a comprehensive eye exam by an ophthalmologist, and a clear understanding of the risks and benefits of the procedure should be discussed with the patient before undergoing the procedure.

Mosquito eyes

 Mosquitoes, like many other insects, have compound eyes. Compound eyes are made up of numerous individual photoreceptor units called ommatidia. Each ommatidium consists of a lens, a cornea, a crystalline cone, and a light-sensitive receptor cell.  Mosquito compound eyes are typically large in proportion to their body size and are positioned on the sides of their head. They have a spherical shape and provide mosquitoes with a wide field of vision, allowing them to detect movement in different directions.  The compound eyes of mosquitoes are designed primarily for detecting changes in light intensity and movement rather than forming detailed images. Each ommatidium captures a small part of the overall image, and the mosquito's brain processes the input from multiple ommatidia to form a composite picture of its surroundings. Mosquitoes are attracted to certain stimuli such as heat, carbon dioxide, and chemicals in human sweat, which help them locate potential hosts for blood meals. T

Contact lens parameters

 Contact lenses are medical devices that are worn directly on the cornea of the eye to correct vision or for cosmetic purposes. There are various parameters associated with contact lenses that are important for fitting and prescribing the right lenses for individuals. Here are some common parameters: 1. Power (Refraction): Contact lenses are available in different powers to correct nearsightedness (myopia), farsightedness (hyperopia), astigmatism, and presbyopia. The power is measured in diopters (D) and can be positive (+) or negative (-) depending on the type of vision correction needed. 2. Base Curve (BC): The base curve determines the curvature of the contact lens. It is typically measured in millimeters (mm) and represents the curvature of the inner surface of the lens. The base curve is chosen to match the curvature of the cornea for proper fit and comfort. 3. Diameter (DIA): The diameter of a contact lens is the measurement across the lens from edge to edge. It is usually measur

Base Curve of contact Lens

The base curve of a contact lens refers to the curvature of the back surface of the lens. It is measured in millimeters and is one of the main characteristics of a contact lens. The base curve is important because it determines how well the lens will fit on the eye. A lens with a base curve that is too flat may not conform to the shape of the eye and may cause discomfort or irritation. On the other hand, a lens with a base curve that is too steep may be difficult to insert and remove and may cause lens dislocation or other problems. To find the right base curve for a contact lens, an optometrist will measure the curvature of the eye using a tool called a keratometer. This instrument measures the curvature of the front surface of the eye (the cornea) and helps the optometrist determine the appropriate base curve for the lens. In addition to the base curve, other factors that can affect the fit and comfort of a contact lens include the diameter of the lens and the material o
