Astigmatism is a typical vision problem that occurs when the shape of the cornea is distorted due to injuries or other causes. With astigmatism, the lenses of the eye or the cornea curves. This irregular curve can change the way light refracts or passes through your retina. This causes hazy, fluffy, or twisted vision. Farsightedness and partial blindness are two different sorts of issues with the way light goes to your retina. Farsightedness is called hyperopia. Partial blindness is called astigmatism.
Types: There are two types of Astigmatisms. These are:
- Corneal astigmatism: It happens when your cornea itself is distorted.
- Lenticular astigmatism: Lenticular astigmatism happens when your lens is distorted.
Risks: Astigmatism can happen in youngsters and grown-ups. Your danger of creating astigmatism might be higher if you have any of the following:
- A family history of astigmatism or other eye issues like dislocation of the cornea.
- Scarring or diminishing of your cornea
- Excessive partial blindness, which makes foggy vision at a separation
- Excessive farsightedness, which makes hazy close-up vision
- A past of eye surgeries, for example, cataract surgery (surgical expulsion of a blurred focal point)
Symptoms: The side effects of astigmatism include:
- Hazy, Bended, Or Fluffy Vision At All Separations (Close-Up And Far Away)
- Trouble seeing during evening
- Lazy eye
- Irritation in the eye
- Cerebral Pains
- Visual Acuity Assessment Test: Patients are required to read letters from a graph at a particular distance to decide how well they can see the letters.
- Refraction Test: A refraction test uses a machine called an optical refractor. The machine has various remedial glass lenses that are used to read an outline while looking through lenses on the optical refractor.
- Keratometry: Keratometry is a route for your specialist to measure the bend of your cornea. They will do this by taking a look at your eye through a keratometer.
- Corrective Lenses: Remedial eyeglasses and contact lenses prescribed by a specialist are the most well-known and least obtrusive solution for astigmatism.
- Orthokeratology: Orthokeratology is a treatment that uses contact lenses to correct the deformation and flow of your cornea. You will wear inflexible contact lenses for certain time-periods. It is easier to wear them while you are sleeping and remove them during the day.
Surgery: Your specialist may suggest refractive surgery if your case is a serious one. This kind of surgery includes use of lasers or little blades to reshape your cornea. This will correct astigmatism permanently. The three basic surgeries for astigmatism are:
- Laser in situ keratomileusis (LASIK)
- Photorefractive keratectomy (PRK)
- Spiral keratotomy (RK).
All these surgeries might carry some risks depending upon the symptoms of your problem. As innovation advances, it is very important for the patient to explore more options before choosing which refractive surgery is a good fit for him or her. If you wish to discuss about any specific problem, you can consult an Ophthalmologist.

I've been suffering from (SEES) sharp edge eyes syndrome where I can not look at any sharp and pointed object or corners of any object. There is no headache, its just a strong urge to look away from it and even than there could be a discomfort because of its image being still there in my memory. Sometimes I might feel normal looking at such objects but suddenly I became aware of it and same thing happens. I've suffering from it since my childhood, now I am 40. This has been a big hurdle in my academic as well as professional life. Please suggest ant solution if there is any. Thank You.

Considering lasik lasers (for eye glass removal) for their eye glass removal. One must read this as it has some serious implications/complications if done in haste.
There are lot of benefits by being myopic (eye power less than -3 d) and disadvantages in going for lasik laser in young age with low eye power.
You may never need glasses after 40 years (presbyopia) of age for reading if you use glasses or contact lens now instead of getting your glasses removed by lasik lasers (for powers less than - 3d and around -3d) but after lasers you may need the same so going for laser may keep you free from glass for roughly 15 to 20 years only. The myopia can come back even after lasik surgery.
There are variety of complications with lasik lasers like glare, halo and problem in colour contrast, dry eyes, problem in night vision, serious complications like corneal ectasia (may need corneal transplant) although advancement in lasers has minimized these issues still one should refrain from it since the percentage of side effects are highly underplayed
The disadvantages according to my experience outweighs the benefits in young age for those with low myopia (-3d) and considering the risks involved and amount of side effects associated with it which are highly under reported by the doctor.
Lasik operated emmetropic (having normal eye power) are not allowed in airforce, railways and army.
If you are young and advised for lasik in haste without giving due consideration about thickness of cornea, it may result in complications after 5 years and can affect rest of your life.
If you are having high eye power (more than -3d) then there are various issue which should be taken in consideration.
First and foremost, the corneal (outer membrane for eye) thickness must be measured by pachymetry. Indians have a thinner cornea around 400 to 450 micron as compared to western population (around 600 micron).
The critical thickness of cornea must be above 300 micron even after lasik lasers to avoid/minimize future complications.
Since laser burns the cornea, for removing every 1d of eye power, there is a reduction in 35 micron thickness in cornea.
Indians with average thickness of 400 to 450 micron thickness can only go upto 35*5= 175 micron reduction to ensure that their corneal thickness remains above crucial thickness of 300 micron.
So patients are advised to take a independent opinion from a experienced ophthalmologist preferably before going for lasik laser since procedure done on wrongly selected patient can lead to life long complication for the patient.
One can use contact lenses which have become quite advanced with time, if one does not want glasses. All that glitters is not gold and not every side effect can be predicted.
