If you are experiencing visual impairment or refractive errors, you may experience glasses or contact lenses. Although eye glasses can be considered as the first treatment option, they cannot resolve vision problems unfortunately. In fact, glasses or medical lenses are temporarily able to correct refractive errors in the eye. Despite the benefits of eye glasses, continuous use of them can have many disadvantages. Some of these disadvantages include:
Today, with the advancement of science in the field of ophthalmology, we are witnessing the development and development of new methods of laser eye surgery that are capable of treating refractive errors of the eye permanently and can be a very suitable alternative to the use of eye glasses. Also, with the advancement of technology used in eye surgery, laser eye surgery is much more reliable and less risky than before.
Refined TransPRK action is the latest type of eye surgery that was first developed by Dr. Adib Moghaddam. Refined TransPRK is a more advanced and improved TRP technique. In fact, in this method, the laser beam is adjusted for each patient individually, based on statistical and optical parameters.
Based on the latest research and scientific findings in the Refined TransPRK, the patient’s demographic characteristics (such as age and sex) and the patient’s optic characteristics (such as refractive errors, refractive errors, corneal thickness, etc.) are used to treat each patient. They are considered as the main parameters for laser radiation regulation, and treatment for each patient is designed. From each eye, there are 8 to 10 consecutive scans, and the surgeon uses the most accurate scan to adjust the eyesight. Laser radiation is performed only once, and the epithelial layer and cornea stroma are in a single laser stage. Then, an anesthetic drop was first used to perform the procedure, and the eyes were washed with a balanced saline solution. In this practice, there is no need to use alcohol and do not cut, and cleansing is done entirely using an excimer laser.
One of the remarkable differences in the performance of Refined TransPRK with other methods is different postoperative outcomes. As a result of Refined TransPRK, night vision and daytime vision quality increases, and supra vision or pilotage vision is seen in 99% of patients. The pilot’s vision means the 10/11 vision is up. 33% of the patients find transplantation 15.15 or more than 10.10 after the TRP reprint.

Today, with the advent of science and technology in the field of ophthalmology, we are witnessing the progression and expansion of new methods and methods of eye surgery. Also, with the advancement of science and technology, eye surgery is safer and less risky than before, with the risk of infection and its side effects greatly reduced. However, few complications after the operation of the eye, especially in the early days of recovery, may occur when enough rest and time passes. One of the most common and natural side effects of the post-operative eye is eye sensitivity to light, which may be of concern to patients who do not have enough information on eye surgery and recovery afterwards.
If you experience light sensitivity in the days following eye surgery, it may be due to one or a combination of reasons. Most commonly, sensitivity is caused by swelling of the corneal tissue in response to the damage caused during the creation of the corneal flap. This flap heals relatively quickly after surgery and rarely results in complications, but during this time, the healing process tends to make patients hypersensitive to bright lights. At the same time, patients also tend to have dry eyes in the early stages of recovery, further exposing the tissues to discomfort from environmental factors including light.
Patients who have post-operative light sensitivity describe the feeling as one of discomfort when exposed to bright light, forcing them to shield their eyes or look away. The light source can be natural or synthetic, such as from the sun or from an indoor light fixture. The severity of discomfort and occasions for it vary, depending on the cause of sensitivity and the patient’s individual tolerance. In some cases, patients may need to avoid all but dim lights for the first few days of recovery, while other patients can comfortably endure most levels of light without issue. Although no patient can necessarily predict his or her precise side effects, a few basic precautions can help everyone enjoy a more comfortable recovery.
Currently, surgical methods have already improved the side effects of treatment significantly. For instance, by cooling the cornea after LASIK and by prescribing anesthetic eye drops, an experienced ophthalmologist can reduce sensitivity in both severity and duration. During recovery, a patient can take additional steps to curb discomfort:

There are various causes of cataract besides age old age, cataract in young people happen too! You might think that only older folks get cataract. But babies and children can get them, too. Cataract—clouding of the eye’s naturally clear lens—can rob you of your vision. Although the exact cause is unclear, in most cases, cataract is associated with people age 60 and above. However, there have been cases of cataract in young people as well.
Types of cataract include:
Nuclear Cataract: Also called a nuclear sclerotic cataract, this is the kind doctors see most. Anyone who lives long enough usually ends up with one. They form in the center of the lens, known as the nucleus.
Congenital Cataract: These are cataract you’re born with or that form when you’re a child. Some are linked to your genes, and others are due to an illness, like rubella, that your mother had during pregnancy.
Posterior Subscapular Cataract: These cataract form just inside the back of your lens capsule — the part of your eye that surrounds the lens and holds it in place. They’re directly in the path of light as it passes through the lens.
They’re quicker to come on than other cataract, and you may get symptoms within months. They affect your close-up vision and make it harder to see in bright lighting.
Traumatic Cataract: Many kinds of injuries can lead to a cataract. You can get one if you’re hit in the eye by a ball or get hurt from a burn, chemical, or splinter. The cataract could come on soon after the injury or not show up until years later.
Secondary Cataract: When another condition or a medical treatment leads to a cataract, doctors call it secondary. Diabetes, taking steroids like prednisone, and even cataract surgery are possible causes.
Radiation Cataract: You may know it’s important to protect your skin from the sun’s ultraviolet (UV) radiation, but it can take a toll on your eyes, too. You can sometimes get cataract if you spend too much time in the sun without eye protection. People who work outdoors are more likely to get this kind of cataract. To prevent it, wear sunglasses with 100% UVA and UVB protection. Cataract are also a possible side effect from radiation therapy for cancer.
Lamellar or Zonular Cataract: This type typically shows up in younger children and in both eyes. The genes that cause them are passed from parent to child. These cataract form fine white dots in the middle of the lens and Over time, the whole center of the lens may turn white.
Although cataract in young people are not common, it is important to know their potential causes:
Healthy dietary choices may help reduce the risk of cataract at any age. Scientists propose that cataract formation results from oxidative changes in the human lens. Nutrition studies support this idea in that fruits and vegetables high in antioxidants may help prevent certain types of cataract.
Consider a healthy, higher dietary intake of:

Cataract surgery is a procedure to remove the lens of your eye and, in most cases, replace it with an artificial lens. Normally, the lens of your eye is clear. A cataract causes the lens to become cloudy, which eventually affects your vision. Cataract surgery is performed by an eye doctor (ophthalmologist) on an outpatient basis, which means you don’t have to stay in the hospital after the surgery. Cataract surgery can be done traditionally using ultrasound energy to remove the cloudy lens or it can be removed with laser-assisted technology. Cataract surgery is very common and is generally a safe procedure.
Signs and symptoms of cataracts include:
To prepare for your cataract surgery, you may be asked to:

Presbyopia is the gradual loss of your eyes’ ability to focus on nearby objects. It’s a natural, often annoying part of aging. Presbyopia usually becomes noticeable in your early to mid-40s and continues to worsen until around age 65. You may become aware of presbyopia when you start holding books and newspapers at arm’s length to be able to read them. A basic eye exam can confirm presbyopia. You can correct the condition with eyeglasses or contact lenses. You might also consider surgery.
Presbyopia develops gradually. You may first notice these signs and symptoms after age 40:
You may notice these symptoms are worse if you are tired or are in an area with dim lighting.
The goal of treatment is to compensate for the inability of your eyes to focus on nearby objects. Treatment options include wearing corrective eyeglasses (spectacle lenses) or contact lenses, undergoing refractive surgery, or getting lens implants for presbyopia. Talk with your doctor about the possible side effects, as this procedure is not reversible. You might want to try monovision contact lenses for a while before you commit to surgery. Refractive surgical procedures include:
Recovery from LASIK surgery is usually more rapid and less painful than other corneal surgeries.

Normally, images are clearly focused on the retina in the back of your eye because the light rays are bent properly to contact the retinal surface. With nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly and it ends up being focused elsewhere, resulting in blurred vision. Traditionally, the blurred vision is corrected by bending (refracting) light rays with glasses or contact lenses. But reshaping the cornea itself also will provide the necessary refraction.
LASIK eye surgery can be an alternative to glasses or contact lenses done for the correction of certain common vision problems. LASIK (laser-assisted in situ keratomileusis) is a type of laser refractive surgery – the best known and most commonly performed. In general, a special type of cutting laser is used to precisely change the shape of your cornea – the dome-shaped transparent tissue at the front of your eye – to improve vision.
LASIK surgery may be an option for the correction of one of these vision problems:
If you’re considering LASIK surgery, you probably already wear glasses or contact lenses. Your eye doctor will talk with you about whether LASIK surgery or another similar refractive procedure is an option that will work for you.

Transepithelial PhotoRefractive Keratectomy (or TransPRK for short), represents a very recent iteration of laser refractive surgery. The evolution of this form of surgery started with PRK, which was soon overtaken by LASIK, or laser in situ keratomileusis. The reasons for this takeover were that LASIK offered much faster recovery of vision and eye comfort than PRK, where recovery was delayed by the need for the surface cells of the cornea to heal. There is also less risk of corneal scarring and refractive regression with LASIK compared with PRK. Correct your vision without the need to cut a cornea flap with no touch, no blade TransPRK However, LASIK may not be suitable for everyone. Hence, TransPRK has been introduced as a form of laser surface ablation to cater for the group of individuals who are not suitable for LASIK. TransPRK is a non-invasive, no blade surface-based procedure; a safer procedure that is suitable for almost everyone, especially if you have been rejected for LASIK. TransPRK may be a second chance for patients with thin cornea and for patients who have had complications from LASIK and Epi-LASIK.
TransPRK is a new one-step, incision-free procedure. Using the one laser, the epithelium (the regenerative outer surface of the eye) is gently removed and the cornea precisely reshaped. Our state-of-the-art laser concentrates a ‘cool’ ultraviolet light beam and high-energy pulses on the cornea. The laser removes a microscopic amount of stromal tissue, calculated on the pre-operative analysis and determination of the power of your eye. The procedure enables the contour of the cornea to be reshaped in less than one minute. After the cornea of the eye has been re-contoured, clear contact lenses are used to reduce discomfort during the healing of the epithelium and provide protection for the eye. The contact lenses are usually removed 3-4 days after surgery at your first post-operative assessment. The Sydney Eye Clinic is able to provide the necessary medication to minimise any discomfort during your recovery.
In PRK with older techniques required improved recovery time for corneal surface cells. But with the advent of technology and new techniques, the TransPRK operation was introduced, which could almost certainly overcome the shortcomings and limitations of older methods. In PRK, the patient experienced a lot of pain and burning after surgery and during his recovery. The patient also had a blurred vision for a long time. But nowadays, immediately after the laser treatment, your vision will already be clearer than normal. However, your vision will be slightly blur over the next 3 to 4 days because the surface cells (Epithelium) will take some time to regenerate over the corneal surface which is not as smooth as before. A transparent thin contact lens is placed over the eye immediately after surgery to protect the cornea and speed up the recovery of these epithelial cells. Your vision will continue to improve in the following week and you should be able to see tremendous improvement by the end of this period.

Astigmatism is a common vision condition that causes blurred vision. It occurs when the cornea (the clear front cover of the eye) is irregularly shaped or sometimes because of the curvature of the lens inside the eye.
An irregularly shaped cornea or lens prevents light from focusing properly on the retina, the light-sensitive surface at the back of the eye. As a result, vision becomes blurred at any distance. This can lead to eye discomfort and headaches.
Astigmatism frequently occurs with other vision conditions like myopia (nearsightedness) and hyperopia (farsightedness). Together these vision conditions are referred to as refractive errors because they affect how the eyes bend or “refract” light. The specific cause of astigmatism is unknown. It can be hereditary and is usually present from birth. It can decrease or increase over time.
An optometrist can diagnose an astigmatism through a comprehensive eye examination. Testing for astigmatism measures how the eyes focus light and determines the power of any optical lenses needed to improve vision. This examination may include:
With the information from these tests, your optometrist can determine if you have astigmatism. Your optometrist will use these findings, combined with those of other tests performed, to determine the power of any lens correction you need to provide clear, comfortable vision. Once testing is complete, your optometrist can discuss treatment options.
People with astigmatism have several options to regain clear vision. They include:
The Refined TransPRK method is the latest therapeutic technique to correct astigmatism. In this method, the cornea is completely corrected for the treatment of astigmatism. One of the unique features of the Refined TransPRK is to perfectly match the patient’s state of affairs, so that the laser beam is adjusted individually for each individual, tailored to the demographic parameters (such as age and gender) and the individual’s optic characteristics. As a result, the success rate of this surgical procedure was very high compared to other surgical procedures.
