Description
LASIK is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses. LASIK surgery is a type of refractive eye surgery. Normally, the rays of light entering the eye are brought to a precise focus on the retina – the light sensitive layer lining the back of the eye. When such a focus is not achieved, a refractive error results and vision is not clear. These imperfections in the focusing power of the eye are called refractive errors. The common refractive errors are Myopia, or Nearsightedness (Close objects look clear, but distant objects appear blurred), Hyperopia, or Farsightedness (People with hyperopia can usually see distant objects well, but have trouble focusing on nearby objects) and Astigmatism

(distorts or blurs vision for both near and far objects) Pre Surgery Prior to LASIK Surgery, a comprehensive eye examination will be done to ensure whether you are a right candidate for undergoing LASIK treatment or not.
The pre-LASIK vision correction evaluation should include History taking, Visual Acuity Testing , Refraction , Keratometry (measurement of corneal curvature) , Slit Lamp Examination by a Lasik Surgeon, Pupillary measurements , Tear Film Analysis , Glaucoma Testing , Pachymetry (measurement of corneal thickness) , Detailed Retinal Evaluation with Dilatation , Corneal Topography , FACT, LVCA (Low contrast Visual Acuity) , Aberrometry Test & Pentacam Test. This whole process will take around two to two and half hour time for evaluation. For your own safety patient’s attendant need to be with him because after tests you not be able to self-drive home after the tests , as the vision may be slightly blurry for a couple of hours. The most preferable age for Lasik surgery is after 18 …show more content…
years. After evaluation doctor will decide which type of Lasik procedure will be suitable for you as there are many type of Lasik procedure like Customized , Intralase , Flapless bladeless surgery otherwise if Lasik is not suitable for your eye than there are other options to remove your spectacles like PRK , ICL etc. which will be prescribed by your doctor only. Surgery will be done under local anesthesia through eye drops and the procedure will take around 15minutes per eye and patient will be discharge on the same day. Before surgery doctor will advise to instill some antibiotics eye drops 2 to 3 days prior to your scheduled surgery date and some precautions need to follow before and on the day of surgery like don’t wear contact lenses 48 hours before surgery date, head wash on the day of surgery, no cosmetics will be applied on face including deodorants or perfumes. Surgery & Hospitalization This is an outpatient procedure that usually takes 10 - 15 minutes per eye. The actual laser treatment usually takes a few seconds. First you will lie on the motorized bed. The eyes are anesthetized with local anesthetic eye drops only. The head is positioned under the laser. A soft clip (Speculam) keeps the eyelids gently and comfortably open during the treatment. You will be asked to look at a soothing green blinking light during the entire procedure. During the treatment, an instrument called the microkeratome creates a corneal flap to make it a painless procedure. The computerized Excimer laser uses a beam of light to gently reshape the cornea so as to alter its curvature to the desired extent. The flap when replaced on the new corneal curvature allows images to be sharply focused on the retina. The goal is to eliminate or greatly reduce the dependence on glasses or contact lenses. A post - procedure eye examination is performed and eye drops are prescribed. There may be mild discomfort for a few hours after the procedure. Post- Discharge After Surgery doctor advised you to wear black glasses atleast for a week , don’t rub eyes , don’t splash water directly into eyes , don’t use eye makeup , hair color for a month , don’t shave, follow proper medication as prescribed by a doctor.
Follow up visits will be followed as prescribed by doctor. You can resume most normal activities immediately after surgery. However, for at least two weeks you will need to avoid activities that would cause perspiration to run into the eyes. You should wear safety glasses while playing contact sports whether or not you have had surgery. But, if you do not routinely wear safety glasses, your surgeon may recommend wearing them for at least one month after LASIK. You will also need to avoid such activities as contact sports and swimming for several weeks. It is important that you also consult your doctor about limitations on activities after
LASIK. Fast visual recovery characterizes this operation. Most patients achieve good vision the day after surgery and find that their eyes feel fairly normal within a day. However, vision can continue to improve, and best vision can still take two to three months to occur. Most patients who have LASIK do not wear glasses for their daily activities. However, patients may need to wear reading glasses if they are over the age of 40. This is caused by the normal aging of the eye known as presbyopia. This condition occurs with or without LASIK. Some patients may need a minimal prescription for some activities such as night driving. Side Effects , Chances of Recurrence & Complications As with any surgery, LASIK surgery carries risks, including: • Undercorrection, overcorrection or astigmatism. If the laser removes too little or too much tissue from your eye, you won't get the clearer vision you wanted. Similarly, uneven tissue removal can result in astigmatism. • Vision disturbances. After surgery you may have difficulty seeing at night. You might notice glare, halos around bright lights or double vision. • Persistent Dry eyes. LASIK surgery causes a temporary decrease in tear production. As your eyes heal, they might feel unusually dry. • Flap problems. Folding back or removing the flap from the front of your eye during surgery can cause complications, including infection, excess tears and swelling. • Have a condition that may impair your ability to heal. Diseases that affect your immune system, including autoimmune diseases (rheumatoid arthritis, lupus and others) and immunodeficiency diseases (HIV), increase the risk of incomplete healing, infection and other complications. Taking an immunosuppressive medication also increases the risk of a poor outcome after LASIK surgery. • Have anatomic concerns. LASIK surgery may be inappropriate if your corneas are too thin, your corneal surface is extremely irregular, or you have a condition in which the cornea thins and gradually bulges outward into a cone shape (keratoconus). LASIK surgery also may not be an appropriate option if you have an abnormal lid position, deep-set eyes or other anatomic concerns. • Have unstable vision. You may not be eligible for LASIK surgery if the pressure inside your eye is too high or the quality of your vision is fluctuating or getting worse. • Are pregnant or breast-feeding. Vision can fluctuate during pregnancy and breast-feeding, making the outcome of LASIK surgery less certain.
The first laparoscopic cholecystectomy (LC) using keyhole approach was done by Professor Mouret of Lyon, France in 1987, when he was completing a gynecologic laparoscopy on a woman also suffering from symptomatic gall stones, he removed it laparoscopically instead of opening up. Dr. Eddie Reddick reported 100 cases of laparoscopic cholecystectomy in 1989. The classical four port technique of LC as described by Reddick became the most widely adopted technique.
Optometrists have accepted vision therapy, which is a medical treatment for optical muscle disabilities, as a feasible treatment used for eye related problems; claiming the treatment can strengthen vision and give the patient the opportunity to understand visuals quicker and clearer (Press). Vision therapy originated in the 1950s and over the past 25 years, has gained popularity, mainly because of new technological innovations in the field of treatment. Generally, vision therapy is prescribed as a measure mainly for people between the ages of 3 and 18. With the results from a comprehensive series of eye tests, the optometrist can work with the patient using special instruments—prisms, filters, occluders, and eye lenses—and strengthen the eye muscles, thus improving sight. According to optometrists in favor of vision therapy, these methods of treatment using these instruments function as safer routes to repair eye disabilities. Although vision therapy can yield favorable results, the practice as a treatment for innate eye disabilities has been in hot debate lately; as it can exceed $8000 and insurance companies do not cover the treatment. For decades, insurance companies have refused to accept vision therapy as a legitimate method for repairing eyesight (Boink). Concomitant with lack of insurance, the cost for a full treatment can exceed $8000, and doctors cannot guarantee a successful outcome. Recently, parents of children with eye related disabilities, such as amblyopia (lazy eye) and strabismus (cross-eye), and doctors have attempted to cooperate with public schools to allow families access to school-funded doctors to practice vision therapy. With a tight budget, most schools cannot afford to supply vision therapy, and a...

Scoliosis surgery is a hard thing to go thru. This surgery is usually conducted by two doctors and their assistants. The doctors purpose of conducting this surgery is to straighten the back. They do this surgery usually in three to four hours for medium to large cases. For someone with scoliosis to need this surgery their curve has to be between 30-50 degrees or more at the time of surgery. For the doctor to do this he/she has to go under the muscle and hold your backbone straight while screwing stainless steel metal rods in your back bone and then glues the large incision
Avoid using cosmetics/makeup products – you may be asked to stop wearing makeup products the day before surgery to minimize the risk of possible infections before and after the
As I was out my Mom and Dad stayed and waited the whole time, a total of 3 hours. Normal Strabismus surgeries take 1-2 hours, mine took longer because of how bad the turn was in my eyes. The turn of both eyes was the same, a 66 degree turn, normal eyes have the degree between 3-7, you can't even noticed them. The turn was also affecting both of my eyes so I could switch which one I wanted my focus out of. My vision was never effected, I have always had 20/20 vision that's another reason I was upset I had been stuck with glasses and contacts my whole
The time required for recovery and recuperation in laser treatment is less than that required for surgery.
Let your doctor know if you're taking any prescription drugs, over-the-counter drugs, or supplements. Your doctor might recommend that you avoid taking those 48 to 72 hours before the procedure. You should also avoid
In order to have LASIK eye surgery, the patient first needs to go to an eye doctor for a pre-surgical eye exam. However, the patient needs to meet the following criteria: be at least 18 years old, be in good health, should not have any eye infections or injury, should not be nursing or pregnant, should not suffer from dry eyes, and must not wear contact lenses for a certain period of time. In the pre-surgical eye exam, the doctor will determine which areas of the cornea need reshaping by using highly specialized instruments. The doctor will also take note of irregularities in the eye before the surgery.
Barrett's esophagus (BE) is a premalignant condition that progresses to esophageal adenocarcinoma through an intermediate stage known as dysplasia. Current guidelines recommend that individuals with BE undergo periodic endoscopic surveillance with white-light endoscopy-WLE and random, four-quadrant biopsies to identify and treat dysplasia. However, this surveillance strategy is limited by random sampling error and low sensitivity. Surveillance with random biopsies can miss up to 43-57% of early neoplasia. This review will discuss the current role of two advanced imaging techniques i.e. Confocal Laser Endomicroscopy (CLE) and Volumetric Laser Endoscopy (VLE) in screening and surveillance for BE. CLE has the highest accuracy of any endoscopic technique and increases the diagnostic yield and sensitivity for dysplasia and
Laser skin resurfacing may not be for everyone. If laser resurfacing is the best treatment for you, we may ask you to avoid taking any dietary supplements, aspiring, vitamin E or ibuprofen for 10 days before the treatment. If you smoke, you should quit at least two weeks before treatment because smoking inhibits healing. If you have issues with fever blisters or cold sores, you should inform our specialist. The treatment is an outpatient procedure, and you can go home afterwards.
Many brides have beauty treatments planned before their wedding. Make sure you discuss any planned treatments with your eyebrow artist. Some treatments such as anti-wrinkle injections need to be completed a two to four weeks before your microblading sessions. Some other treatments such as scrubs or peels need to be done two weeks after your eyebrow tattoo has been completed as they may interfere with the healing
Some cases cause for surgery which consists of replacing the damage or clouded lens with an artificial

...he cornea is deformed so that its surface is oval instead of spherical. Light rays are distorted at the entrance of the eye. This produces a blurred image and is known as astigmatism. To correct it, glasses are given a nonspherical or cylindrical curvature. Cross-eyes and walleyes are produced when both eyes do not work together because of weakness of the eye muscles.
