The Importance of Pre-Surgery Testing

The Importance of Pre-Surgery Testing

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.

My eyes are paining very badly and the colour of eyes have turned red. So now what should I do.

Eyes appear red because the vessels at the surface of the white portion of the eye (sclera) become swollen. Vessels may swell due to: • Eye dryness • Too much sun exposure • Dust or other particles in the eye • Allergies • Infection • Injury Homoeopathic medicine EUPHRASIA 30 ( Dr Reckeweg) Drink 2 drops direct on tongue every 2-3 hrly EUPHRASIA EYEDROPS ( SBL ) pour into eyes 1-2 drops 3 times daily If no relief within 2 days,please cosult an Eye specialist for physical examination.

Having eye sight and want to remove the glasses so please help me Tell me how to decrease eye sight.

There is no medication or food for improving eyesight or to get rid of glasses. If not interested in glasses then you can try a. Contact lens b. Lasik laser as your age is now 17 years so your number will not increase much now whether you wear glasses or not as number becomes stable at age of 18-20 yrs. Having said that I advise you to eat balanced diet including green vegetables and seasonal fruits for keeping eyes and body healthy. As you are not comfortable with contact lens then go for lasik. Lasik is a very easy and painless procedure. If you want to get rid of glasses then go for lasik.

FICO, DNB Ophtalmology

Hello lybrate-user. Operations done to remove the refractive error (power) of the eyes are known as refractive surgery (lasik). There are certain basic criteria that most patients need to fulfill before they can safely undergo refractive surgery. To enumerate, they are: (1) stability of refraction: the power of the eyes should have become stable for a period of 1.5 years minimum without any change. (2) curvature of the cornea should be tested by a technique which is known as topography. (3) thickness of the cornea should be measured by a test known as pachymetry. The minimum thickness required is 550 microns. (4) dilated retina evaluation: this is one of the most important tests that should be performed by a trained retina specialist. This test helps in detection of any offensive lesion on the central or peripheral retina. In case of any retinal abnormality, these should be treated before undergoing the surgery for number reduction. (5) there should be no pre-existent corneal abnormality. (example: corneal scar, opacity, defect, etc.) another important suggestion is that whenever you go for the assessment (the above mentioned tests), you should discontinue the use of contact lenses at least 4 weeks prior to the assessment. The reason for this being that use of contact lens temporarily alters the contour of the cornea. It takes around 3-4 weeks for the restoration of the original corneal contour after removal of the contact lens. Another important point is that you, as a patient, should be compliant to put post operative medication in your eyes for at least 2 months. There is bound to be some discomfort, watering, foreign body sensation, pain after the surgery in most cases-you should be ready to tolerate that. A leave from work for 7-10 days after the surgery should be generally sufficient. Last but not the least, you should set realistic expectations from this surgery. Though extremely rare, there is a remote possibility that the surgery may need to be repeated. Also, the need for subsequent treatment for the eye may be required. Thus, you should be compliant enough to trust and follow your eye specialist. In case you have any other queries, feel free to contact me via the audio/video facility offered by lybrate. Hope my suggestions help you, take care, regards.

What are the symptoms for glaucoma. How could I know that, I am not affected or affected by it. Is it a curable one?

Fellowship in Comprehensive Ophthalmology, DOMS
Ophthalmologist, Sangrur
Symptoms of glaucoma are decreased vision in acute cases, photophobia, pain etc. But many of glaucoma patients do not have any sumptoms and they are diagnosed on routine eye check up. To know glaucoma, you have to consult eye specilist and get retinal (optic disc, and iop) evaluation done. Glaucoma can be managed by medicines.

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?

FICO, DNB Ophtalmology

Hi. I have a few suggestions for you regarding the usage of computers, mobile phones and books. Follow the rule of" 20" this means that every 20 minutes, take a gap of 20 seconds, blink your eyes actively 20 times and focus at an object which is minimum 20 feet away. This will help in relieving your eyes from the continuous strain that is caused due to staring. Staring at the computer continuously causes us to subconsciously blink less than normal. This causes the tear film on the surface of the eye to dry up. The result of this is pain, discomfort, etc. Another suggestions regarding the usage of computers is to maintain a proper posture. The computer must be positioned at the same height as your eye level. The neck should not be inadvertently flexed or extended. Roughly, an angle of 90 degrees should be maintained between your upper body and thighs. Likewise, a similar angle (90 degrees) should be maintained between your lower legs and thighs. Also the angle between your hands and arms should be roughly 90 degrees. This is the healthy ergonomic way of sitting while using a computer. Maintenance of proper posture would help in further relieving the symptoms of eye discomfort and pain. All these suggestions may take a while to sink in and imbibe in your routine. Once followed, they are sure to work wonders for you. Redness of the eyes has multiple causes associated with it. To enumerate a few common causes: (1) allergy of the eye. It is usually caused by improper eye hygiene. There is a tendency to rub the eyes with fingers, handkerchief, cloth, etc. This is not a good habit because it tends to transmit lots of virus, bacteria and dust into the eye. Allergy usually presents with symptoms of watering (clear water), redness and itching of the eye. (2) infectious conjunctivitis: this is usually associated with white-yellowish discharge. If so, it would be a good idea to go and show to an eye specialist in person. (3) foreign body lodged in the eye. This is more commonly associated with people who drive 2 wheeler vehicles without protection. It occurs more commonly in one eye. Foreign bodies that commonly get lodged are eyelashes, insect wings, small insects, dust particles, iron particles (more common with people working in the iron industry) the solution for a foreign body lodged in the eye would be better provided by an eye specialist at the clinic. (4) raised intraocular pressure: this is a condition known as glaucoma. It is not so common as the previous mentioned conditions. There is usually associated pain in the eyes. It is commonly bilateral (occurs in both eyes). There is usually a positive family history of glaucoma associated in a majority of the cases. (5) inflammation of the coats of the eyeball. This is known as" uveitis" it is also a relatively less common condition. There is associated pain. It would require a thorough eye checkup including the retina-thus a good idea would be to visit the eye specialist in person. (6) increased blood pressure. This has known to cause redness which is also known as sub-conjunctival hemorrhage. In this regard, a complete ophthalmic evaluation and a systemic evaluation is warranted. From the symptoms and past history described by you, it is likely to be a case of allergy. Maintaining the precautions and hygiene that I mentioned should probably work well for you. You could also use a lubricant eye drop along with an anti-histamine eye drop on a long term basis. (3-4 times daily). Avoid using lotepred eye drops for long term. (strictly) hope my suggestions helped you. Take care

WHEN SHOULD THE CATARACT BE OPERTATED?

MS - Ophthalmology, MBBS
Ophthalmologist, Jaipur
WHEN SHOULD THE CATARACT BE OPERTATED?

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.

What surgery?

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.
 

For over a month now I have been having issues with my eye. Before it was watering and burning. The watering was so bad it was rolling down my check. Its only the one eye really. Now I am having pain like someone is poking me and my check under the eye feels like I was punched and my eye brow hurts too. It seems to also be affecting my migraines. Please help!
