Eye laser Surgery for treatment of eye diseases
Eye laser types are used in laser surgery to treat eye disorders. Not all laser eyes operations are created equal. Depending on the individual’s existing eyesight, age, lifestyle, corneal shape, and a variety of other criteria, their doctor may prescribe any of the several types of laser surgeries. Lasers are not use for only vision correction.Also lasers are used for treatment og glaucoma,retinal disorders,eye channel problems,makula diseases etc. Last new technology lasers are used for eye color changing.This new 8G laser has unique character to target only melanin cells this gives it to protect eye health.

What exactly is laser eye surgery?
Laser eye surgery is a medical treatment that can cure a variety of vision-impairing diseases. Laser eye surgery is not for everyone. People with specific medical disorders, lifestyle choices, or environmental variables may not be candidates for surgery. Laser eye surgery, like any other medical procedure, carries hazards. They are often mild to moderately uncomfortable and will go away with appropriate treatment and time.
In most situations, laser eye surgery entails a surgeon cutting a very thin flap on the surface of the cornea, raising the flap, and then adjusting the eye with a laser to appropriately concentrate light waves on the retina.
Vision recovers within two days, and any further effects normally take two to three weeks to fully recover from. The individual should consult with his doctor before undergoing surgery. Eye laser kinds should be understood, as well as information on problems. As we mentioned before, a different method is laser eye color change surgery for eye color cosmetics.
What are the different types of eye lasers?
Not all laser eye operations are created equal. Depending on the individual’s existing eyesight, age, lifestyle, corneal shape, and a variety of other criteria, their doctor may prescribe any of the several types of laser surgeries. LASIK is the most prevalent. The corneal tissue is altered during surgery to allow light rays to reach the retina. LASIK is intended to treat three of the most frequent laser eye surgery complications: myopia, hyperopia, and astigmatism.
A LASIK surgeon will produce a flap of the corner’s outer layer to provide access to the underlying tissue. This necessitates skill as well as the most recent breakthroughs in digital imaging technology, which allows LASIK doctors to examine detailed photographs of the cornea as they operate. PRK, or photorefractive keratectomy, is an eye operation that employs lasers to reshape the cornea. It is prescribed for patients with mild to severe myopia, hyperopia, or astigmatism. LASEK (laser epithelial keratomileusis) is comparable to PRK. The doctor makes a flap and uses a laser to restructure the cornea. The flap is repaired and allowed to heal before being replaced with a soft contact lens.
LASIK has effectively replaced automated lamellar keratoplasty (ALK) in treating people with severe myopia and some degree of hyperopia.Instead of using a laser, a doctor makes a cut to reshape and straighten the lower layer of the cornea.
Refractive lens exchange, or RLE, is an eye laser procedure aimed at correcting cataracts
The doctor makes a small incision to remove the eye’s natural lens, located at the edge of the cornea. This lens is replaced with a synthetic lens made of silicone or plastic. This is also known as a “clear lens extraction” or “refractive lens replacement” procedure. In addition to working with cataracts, it can also correct extreme hyperopia or myopia and help patients with thin corneas, dry eyes, or other minor vision-related problems.
Other similar procedures include EpiLASIK (a thin layer of the cornea is removed and then replaced); presbyopic lens exchange (PRELEX), in which a very rigid natural lens is replaced with a multifocal, flexible lens to help patients focus better; and Intacs, also known as intracorneal ring segments or ICR, are a variety of eye laser operations in which two crescent-shaped plastic rings are placed on the outermost edge of the cornea, allowing light rays to be refocused on the retina. In the treatment of myopia, ICR has mostly been replaced by laser-based operations.
Let’s also look at some of the conditions that cause vision loss
A sudden loss of vision is a medical emergency. The patient usually applies urgently to ophthalmology clinics with this complaint in one eye. Treatment is directed at the cause; if the treatment is delayed, vision loss progresses rapidly and permanent vision loss, namely blindness, may occur. In situations of low blood pressure caused by extended inactivity, long-term exposure to digital screens, and a shift from dark to light environments, the change from a dark to a light environment might produce abrupt blurred vision. Changes in blood values and abruptly impaired vision, on the other hand, may arise as a sign of some neurological illnesses.
What is sudden vision loss?
Sudden vision loss is defined as a visual loss that occurs within a few seconds, minutes, or days. Vision may become blurred, fade entirely, or be disturbed by flashing lights or floaters in the visual field. A portion of or the full field of view may be impaired. Although sudden vision loss is usually painless, it may be accompanied by eye discomfort, redness, and headaches. Any rapid shift in the visual field is potentially dangerous, even if it just affects a portion of the field or resolves on its own.
Sudden vision loss is a medical emergency, and anyone experiencing it should seek medical assistance immediately. The assessment includes an eye exam as well as a neurological exam to assess the function of the eyes and brain. As part of the first examination, blood testing and brain imaging studies may be ordered. Exams and testing are performed to search for particular eye disorders as well as general medical diseases that might be causing vision loss.
the most prevalent causes of unexpected eyesight loss
Problems in the visual pathway from the eyes to the brain can cause vision loss. Light enters the eye and is turned into electrical impulses that are processed in the brain during the process of seeing. Light enters the eye through the pupil and is translated into electrical impulses by cells in the retina, which is located at the back of the eye. The optic nerves carry these impulses from the eyes to the brain. The occipital lobes of the brain process visual information. Vision loss can occur at any point along this visual pathway.
What is the duration of temporary eyesight loss?
Temporary visual loss can be caused by vascular, neurological (nervous system), or ophthalmological (eye) illnesses. Microemboli induced by carotid artery disease cause transient loss of vision in one eye. It normally takes 2–30 minutes to finish the repair.
How is vision loss in the eye detected?
The existence of an eye illness is indicated by symptoms such as impaired vision, acute eye discomfort, headache, nausea, and redness and swelling of the eyes. Correct symptom observation is critical for accurate diagnosis and therapy. Many neurological illnesses can cause visual problems. Among them are optic neuritis (eye nerve inflammation), optic nerve vessel blockage, eye nerve tumors, pituitary gland tumors, cerebrovascular occlusions, and hereditary disorders.
How can I restore my vision?
Whatever condition is causing visual loss, it is effectively addressed with medicine or surgery. If cataracts are present, for example, surgical treatment is necessary. Unfortunately, not all forms of visual loss are treatable.
What Is the Reason for Blindness?
- high blood pressure
- Yellow spot disease
- unexpected arterial occlusion
- optic nerve inflammation,
- ocular nerve or retinal tumors
- Eye injuries with full thickness
What exactly is heterochromia?
The occurrence of distinct colors of eyes in anatomy is known as heterochromia. It is most commonly observed in the iris, although it can also be found on hair and skin. Heterochromia is caused by an excess or shortage of melanin (pigment). This might be inherited or caused by genetic mosaism, chimerism, sickness, or trauma. Although this difference has frequently been established between heterochrome, one eye totally or partially affects (sectoral heterochromy), generally hereditary (due to mosaism or congenital) or afterwards appearing, with a darker or more open iris or portion of a part. The majority of instances of heterocromy are caused by a congenital illness or condition, or by a physical injury. Following some diseases or traumas, an eye’s color might change.
