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 ophthalmologist suspects 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.

What are the symptoms for glaucoma. How could I know that, I am not affected or affected by it. Is it a curable one?
Am a 27 years old male suffering from redness in my eyes with little pain and blurred vision for the last three years. It stays for 2-3 days and recurred within 15 days or a month. The doctor gave me two eye drops - Winolap and Tearplus. After using prescribed eye drops, I got relief but it recurred within a month. Working on computer, watching TV makes the problem worse. I consulted another doctor who recommended Lotepred eye drop and Lacryl eye gel. Why am I suffering from persistent redness in the eyes?
Total or partial opacification of transparent lens of the eye is termed as cataract. Such opacification essentially occurs in old age but it can occur in children or young age due to diabetes, trauma, congenital causes, use of steroid drops in the eyes or secondary to glaucoma.
Cataract affects vision depending upon its degree and location. Very slight cataract at the posterior pole can obstruct central vision and cause marked glare blindness or inability to read small letters whereas, cataract in the cortical area may take long time to affect vision.
Treatment: no medicines can cure cataract. Once it occurs, it has to be operated.
When to get operated?
When you are professionally blind or unable to carry out your routine duties/work. A driver or a watch repairer has to operate very early due to glare blindness whereas an old lady can wait for some time. It is ideal to get the surgery done with immature or early cataract than to wait for the cataract to get mature. A mature or hypermature cataract is difficult and risky to operate.
Phacoemulsification with ultrasonic rays is the modern method os surgery. You get only 2-3 mm of an incision, no sutures. The lens is emulsified and aspirated and a foldable IOL (lens) is injected by a syringe which unfolds and occupy the same space as your original lens. 10 minutes surgery with practically no pain. This lens lasts for a life time and gives you youthful vision.
The surgery can be performed even in patients with diabetes or hypertension and at any age. Maybe 90-100. Practically no post-op restrictions.
