I am working on computer regularly I got some problem eye itching dryness headache what should I do.
Any patient who needs to undergo cataract surgery must be evaluated in a thorough manner so as to establish the requirement, appropriateness, expected surgical problems, expected benefits and co-morbid conditions having an influence on cataract surgery.
The preoperative assessment consists of -
A test for your existing glasses prescription:
It is useful for your cataract surgeon to know your existing glasses prescription in cases where there is a high refractive error (people who are very short or long sighted), in order to plan to correct this error after cataract surgery.
A full ocular examination: this includes looking at:
- The eyelid anatomy and inflammation.
- The state of the tear film, dry eye changes could make surgery difficult
- The presence of abnormalities in the cornea that could make visualisation of the cataract difficult during surgery.
- The amount of dilation the iris undergoes with dilating drops.
The type of cataract. Soft cataracts can be aspirated. Hard cataracts need more ultra-sound energy and surgical time to break up and remove. White cataracts may need trypan blue staining to visualize the capsule
The measurement of intra-ocular pressure. With this test, we aim to exclude glaucoma and ensure optimal control of immediate pre-operative and intra-operative eye pressures often with extra eye drops that temporarily lower eye pressure.
- Biometry tests: this is a simple pre-operative measurement. It calculates the correct power of artificial intra-ocular lens. They will be implanted into your eye once your cataract is removed.
- Corneal topography: this is a test to map out the corneal curvature in greater detail. It is used prior to premium iol implantation like toric iols either monofocal or multifocal, to ensure avoid postoperative refractive errors. This extra test is only required if the biometry readings show larger than normal differences in keratometry readings.
- Optical coherence tomography (oct): this test allows detailed visualisation of the macula (the central sensitive part of the retina used for fine vision). If the ophthalmologistsuspects any macula changes that may prevent a patient from visual improvement after cataract surgery, he always suggest optical coherence tomography.
- Blood pressure measurements: it is very important to know your blood pressure measurements before your cataract operation. The risk of having a bleed at the back of your eye during cataract surgery (supra-choroidal haemorrhage) is very small (1 in 10000). But is higher if you have uncontrolled blood pressure.
- Blood sugar measurements in diabetic patients: cataract surgery itself does not affect your blood sugar measurements if you are diabetic. A routine checkup of blood sugars in diabetics before cataract surgery is done and the surgery if often delayed if the levels were greater than 20mmol/l as the risk of post-operative infection is higher.
Eye exercises might not necessarily improve eyesight but they help in preventing eye problems and maintaining the correct eyesight level. Eye exercises are usually designed to provide strength to eye muscles, while improving focus, allowing flexible eye movements and helping stimulate the vision centre of the brain.
Palming: This exercise is also very simple to perform. All you have to do is cover your eyes with your palms. Once you have done this, just wait and see that there are no bright flashes of light. If you see that there is a bright flash of light, just wait till they go. This is used primarily to distress the eyes.
Flexing: This is simply rotating your eyes in circles. Roll your eyes in the clockwise direction for one minute and then roll your eyes in the anticlockwise direction for one minute.
Blinking: your eyes get strained due to long hours of sitting at the computer or television and you tend to blink less. Whenever you blink, your eyes stay in darkness for a few microseconds that help to keep the eyes fresh, while reducing eye strain.
Stretching: this is the most common and also one of the easiest to do. It requires you to just look up, hold for two seconds, look down, hold for two seconds and then repeat this procedure for each corner of your eye, which means top-left, top-right, bottom-left and bottom-right corners.
Near and far focusing: this exercise helps in strengthening the eye muscles and improves the vision of your eyes.
It involves the following steps:
- Either sit or stand in a comfortable position for 2-3 minutes
- Bring your thumb about 10 inches in front of your eyes and try to focus on it
- Now try focusing on an object that is about 10-20 feet in front of your eyes
- Try switching between focusing on the other object and your thumb on each deep breath
