If you are thinking that eye examinations are only for people with poor vision, then you are absolutely wrong. We believe that our vision is fine until a visit to the doctor reveals a true situation. An annual eye check-up is necessary to know whether you are suffering from any eye problem before you witness any serious symptom.
Your eye doctor needs to know about your previous history of any allergies, medications or supplements you take, a general update about anyone having eye diseases in your family. The ophthalmologist can easily identify diabetes, glaucoma, high blood pressure and other problems and will recommend you to do a follow up with your physician. You must prepare a list of questions to know about your eye health and ask whether it is right to wear contact lenses on your first visit.
You will be made to read random letters to check your distance and the close vision. The side vision, color recognition shall also be checked. The eye doctor can also use drops to dilate your pupils, which can make eyes light sensitive and caused blurred vision for some time. You need to understand your expectations from the Surgery. Are they realistic? Discuss all the pros and cons in detail with the Surgeon.
If you are a children without risk factor for eye disease,it is recommended that you have an eye examination:
If you are an adult without risk factors for eye disease, it is recommended that you have an eye examination:
If you have a family history of glaucoma or history of diabetes,Hypertention etc you should be examined every year.
Phacoemulsification Surgery is done through 2.2 mm-2.8mm self-sealing incision. The cloudy lens is broken into small pieces and sucked out by an ultrasonic high speed vibrating handpiece. After the Cataract material is removed, the back capsule of the lens is left behind on which a clear foldable intraocular lens is implanted. Most of the times we do the Surgery under topical anesthesia-only eye drops are used to make your eyes numb so that there is no pain felt. As there is no injection near the eye involved, patient feels very comfortable and goes back without any pad and bandage with in a hour.
How will I know that I am suffering from Glaucoma?
Most of the time this condition is detected only upon Routine Eye Examination since there are hardly ever symptoms till very late. Hence all patients at our hospital above 40 years age are screened for the same. The symptoms of this disease may vary from no Symptoms to Eye ache, Headache, red painful Eye and blurred vision. Sometimes early Glaucoma can cause frequent change in spectacles power.
What should be the lifestyle do’s and don’ts for a glaucoma patient?
Not really. There is nothing external influencing the course of Glaucoma. There is no diet restriction. Carry on with our routine lifestyle and just be regular with your medicines. If you have hypertension, diabetes or thyroid disease, it needs to be well controlled. Avoid having excess of tea and coffee as caffeine has been shown to increase eye pressures in some individuals.
Routine eye examination includes-
• Applanation Tonometry-to measure intraocular pressure
• Fundus- documents the changes of Optic Nerve head(disc) while looking at your fundus through pupil
• Gonioscopy- The type of Glaucoma is detected by assessing the angle of an interior chamber of Eye by gonioscopy.
Depending on the level of suspicion, we ask for following confirmatory test:
• Perimetry - computerized visual field (AVF) test to detect areas of fading vision.
• Central corneal thickness-to refine the results of our eye pressure measurements
• Optical Coherence Tomography (OCT)-anatomical documentation of the optic nerve head and nerve fibre layer
How do you treat lazy eye (Amblyopia) in children?
The earlier the treatment, the better the opportunity to reverse the vision Loss. Although the best outcome is achieved if treatment is started before age 5, research has shown that children older than age 10 can show improvement in the affected eye. Before treating Amblyopia, it may be necessary to first treat the underlying cause.
Glasses are commonly prescribed to improve focusing or misalignment of the eyes. Squint Surgery may be performed on the eye muscles to straighten the eyes if non-surgical means are unsuccessful. Eye exercises may be recommended either before or after surgery to correct faulty visual habits associated with strabismus and to teach comfortable use of the Eyes.
The correction may be followed by:
The treatment for Amblyopia requires lot of effort and patience from both the doctors and parents. Both have to work as a team to achieve the desired results.
How many hours of patching is enough to treat Amblyopia?
The mainstay of treating Amblyopia is patching of the dominant (good) Eye, either full or part-time during waking hours. The performance of near activities (Reading, Coloring, hand-held computer games) during treatment may be more stimulating to the brain and produce better or more rapid recovery of vision.
What are the treatment options available for squint?
It is the common name for “strabismus” where the eyes are not aligned in the same direction. Strabismus can be treated in various ways. Depending on the individual case, treatment options include:
What are the complications associated with contact lenses wear?
Excessive wear of Contact Lenses, particularly overnight wear, and poor hygiene is associated with most of the safety concerns. Never ignore any redness, itching, watering if you are wearing Contact Lens and seek advice from the ophthalmologist.
Few complications of Contact Lens are Giant papillary conjunctivitis-allergic, Superior limbic keratoconjunctivitis-dry Eye, Corneal abrasion, Corneal ulcer - keratitis etc. These are not common and can be easily avoided with proper handling and care of your Lenses.
The option of any of above depends on the age, Refractive Error, Eye Condition and Personal Choice.
• Age- Contact Lens and Lasik is not an option for children. They should wear spectacles. Teenagers can use Contact Lens while the minimum age limit for Lasik is 18 years.
• Contact lens is a safe option if a person does not want to wear glasses.
• If Contact Lens do not suit you or find it cumbersome to handle them, Lasik is a good option. It gives you a permanent solution to get rid of your Glasses or Contact Lens. Only the reading or near number may come up later in life after 40 to 45 years of age. There are certain parameters in eye which need to be examined upon prior to opting for Lasik eg- Corneal Thickness, tear film, retina etc. The Ophthalmologist will examine your Eyes in detail and guide you accordingly.
