Ophthalmological Services

High quality personalized eye health services

Visit the Ophthalmologist

A great idea for your eye health is to schedule a visit to an expert such as an ophthalmologist.

An appointment with your own ophthalmologist in a modern clinic for examination, prevention the potential eye problems, means that they are much more likely to be prevented in their early stages, meaning they can be resolved with a simple treatment or where appropriate, a surgery.

How often should you visit an ophthalmologist?

Ideally, an appointment with an ophthalmologist is advisable every two years, unless you use contact lenses, so an annual checkup is usually recommended. More frequent testing should be done if there is a serious medical history or conditions such as diabetes and high blood pressure, diseases that are associated with damage to the lower retina.

Most people only get to see an ophthalmologist only when eye problems have already occurred, but this often maximizes problems that would have been resolved if there had been frequent visits.
Your doctor may also refer you for further screening if conjunctivitis or other types of eye inflammation, chronic dry eyes, rapid eye strain (glaucoma), cataracts or macular degeneration are diagnosed.

Heredity plays an important role in eye diseases. So, for example, if someone in your family has glaucoma or diabetes (headaches), our ophthalmologists can offer special monitoring and referral.

Trust us for the comprehensive services we provide to patients of all ages, the high level of diagnostic, clinical and surgical care.

Some people do not produce sufficient tears for their eyes to be stored at a “handy” state of affairs. tear manufacturing generally decreases as we age. despite the fact that a dry eye may additionally arise in each males and females of all ages, ladies are most affected, specially after menopause. dry eye can also be related to arthritis and followed by way of a dry mouth. humans with dry eyes, dry mouth and arthritis are considered to be afflicted by sjogren’s syndrome. a large style of commonplace pharmaceutical preparations also can cause xerophthalmia reducing tear secretion. people with a dry eye are frequently extra at risk of the toxic side consequences of drugs for the eyes, together with synthetic tears.


  • Stinging or burning eyes
  • Itching
  • Fibrous mucus in or around the eyes (or eye gum)
  • Severe eye inflammation from smoke or wind
  • Lacrimation
  • Problem in fitting contact lenses

Blepharitis (blepharitis) is a commonplace and persistent irritation of the eyelids. the bacteria present inside the skin surface around the eyes, are feasible, in a few people, to broaden at the skin at the base of the eyelashes. this outcomes in eye inflammation. this situation often takes place in human beings who have a bent for oily skin, dandruff or dry eyes. blepharitis can start in early adolescence with the emergence of granulation at the eyelids and retain the relaxation of their life as a chronic condition.


  • Burning
  • Itching
  • Sensitivity to light (photophobia)
  • Foreign frame sensation (stated upon waking)
  • Yellow crusts on the rims of the eyelids

  • More

The retina is a thin layer of tissue in the again of the eye (gambling the position of photographic film to capture visible data). the macula is the critical portion of the retina, a thin layer of photosensitive cells and nerve fibers. the macula is the factor at which mild is focused when you look at an item, it’s miles answerable for sharp vision (details of items) and for colour vision.

Amd (age-associated macular degeneration) it’s far a degenerative situation of the macula. the precise etiology of the ailment stays unknown thus far. it seems with ageing usually in people over 60 years and is one of the maximum critical reasons of vision loss global. in the early degrees of amd, substance deposits are generated beneath the retina. those deposits are known as drusen and they’re typically visible to the opthalmologist at some stage in the examination of the attention fundus. in most instances drusen do not result in extreme imaginative and prescient impairment.

  • More

Cataract (cataract) is a watch sickness that develops with growing older. it’s far the gradual, through the years, clouding of the natural crystalline lens of the eye behind the iris. the herbal lens of the attention is normally obvious so the mild can pass thru to then reach the retina, the rear floor of the attention, for imprinting the optical pulses.

Over the years, consequently, this lens loses its original composition and blurs (senile cataract). this sickness makes its look usually over 60, but does not exclude the incidence of instances and in younger a long time as nicely. exposure to daylight (ultraviolet radiation) and terrible nutrients boost up the disorder.

The principle signs and symptoms of cataract are:

  • Reduced (blurred) vision (remote or close by)
  • Impaired coloration perception (colour belief)
  • Blurred or appreciably reduced assessment sensitivity (evaluation sensitivity)
  • Drastically decreased night imaginative and prescient (night imaginative and prescient)
  • Frequent adjustments in the eyeglass prescription
  • Sensitivity to mild (photophobia)
  • Glare, reflections and halos (halos)

Treating cataract:

At an early level, cataract can be treated with the prescription of glasses. but this answer is certainly transient. the whole removal (treatment) of cataract is really executed via cataract surgical operation.

The most big method is the method of phacoemulsification (phacoemulsification) with ultrasounds. it is a surgical method of excessive protection due to the advanced technology used.

Refractive Abnormalities

Refractive abnormalities refer to…. 

  • More

Refractive abnormalities refer to the most common eye diseases, such as Presbyopia, Myopia, Astigmatism and Hypermetropia.


Presbyopia is an evolutionary hassle and now not a static situation. associated with the declining of near vision. presented on the age of 40-forty five years with a mentioned problem in reading, specifically when there may be low lights. regularly, the problem is transformed to a “disability” (the concept of multifocality ceases to exist) and close to vision is characterized as satisfactory (clear) simplest with unique spectacles.

It’s miles a disorder that happens in each person, irrespective of their intercourse or in the event that they have already got different refractive errors inclusive of myopia, hyperopia and astigmatism. for instance, if myopic humans they experience presbyopia, with a purpose to be able to study, they are pressured to take off their glasses while their myopia is low, or to use glasses with a lower myopia grade, whilst their myopia is excessive. in the end, it’s miles referred to that in human beings with hyperopia, presbyopia may additionally arise at an in advance age.

Presbyopia can be treated with:

  • Presbyopia imaginative and prescient glasses (bifocals or multifocal)
  • Multifocal contact lenses
  • Refractive surgical operation (surgery with excimer laser and the use of unique strategies e.g. presby-lasik and monovision)
  • Surgical procedure to implant a multifocal intraocular lens (intraocular multifocal lens) and changing the crystalline, the herbal lens of the attention, in
  • combination for the removal of cataract


Short-sightedness (myopia) is a completely common refractive mistakes wherein distant vision (remote imaginative and prescient) is very hard. in myopia, light rays from the external surroundings, and hence the photographs of the numerous objects aren’t centered in returned of our eye, i.e. the cornea, as in normal emmetropic eyes however in front of it, so we can not see objects which are far away, absolutely.

Principal causes:

  • Multiplied refractive strength of the eye (refractive myopia)
  • Accelerated sagittal axis of the eye (axial myopia)
  • Heredity (determination of grades and progression of refractive blunders)
  • Analyzing and pc use (contributing to the deterioration of abnormality)
  • Hormonal adjustments (eg at some stage in pregnancy, deterioration of the condition is observed)
  • Environmental elements
  • Congenital glaucoma
  • Spherophakia
  • Optical neuropathy


Astigmatism (astigmatism) is that refractive error of the eye in which the cornea is elliptical (rather than spherical) with asymmetrical curvatures. the incoming rays of mild (optical images) do now not recognition on one point on the retina, as is regular emmetropic eyes but merge into one line forward or backward (e.g., orthogonal snap shots) from the retina.

Astigmatism normally coexists with myopia or hyperopia. more hardly ever, the astigmatism may be due to choppy crystalline lens behind the iris of the attention or to disease of the curvature of the posterior pole (retinal astigmatism).

It also includes because of two one-of-a-kind curvature of corneal meridians (axes of the cornea), i.e. of the front a part of the attention, which instead of having a spherical shape, it has an oval form (like an egg). if the focus of the two pix lies in front of the retina, we’re speaking about myopic astigmatism, and if it lies behind, we are speakme about hyperopic astigmatism.

However it is able to also be mixed. astigmatism may be both clean (while the two axes are perpendicular to every other), or abnormal (when the 2 axes aren’t perpendicular). various pathologies (together with keratoconus) can also worsen the refractive error.


In farsightedness (hyperopia) the close to imaginative and prescient is specially affected however additionally, to a point, the remote imaginative and prescient as nicely. it’s also a frequent refractive mistakes, in which the light beams from the outside surroundings, and hence the photographs of the diverse objects are not targeted in the back of our eye, i.e. onto the retina, as is ordinary emmetropic eyes however in the back of it, leading the eyes to tire without difficulty or not seeing very definitely close to or some distance.

Essential reasons:

  • Decreased refractive electricity of the eye (refractive hyperopia)
  • Decreased sagittal axis of the attention (axial hyperopia)
  • Heredity

Hyperopia commonly occurs at start. it can display a decrease in teenager and put up-adolescent age because of greater adaptability of the eye lens and begins to disturb again at the age of 30-35 years.

Word that presbyopia starts earlier in hyperopia.

Hyperopia may be handled with:

  • Imaginative and prescient spectacles
  • Contact lenses
  • Refractive surgical operation (surgery with excimer laser)
  • Surgical procedure for changing the crystalline, natural eye lens


Glaucoma develops slowly over a length of…

  • More

Glaucoma develops slowly over a length of years. it is a “silent” ailment, for the reason that most patients within the early tiers, regularly do now not display signs. expanded intraocular pressure (normally over 20-22 mmhg) is the primary indication of the existence of the disease, even though there are rare cases while we’ve glaucoma despite regular pressure (low stress glaucoma – the vascular issue performs an vital position).

Glaucoma is as a result of the incapability of the liquid extraction which is normally generated internal the attention. this results in an growth in the intraocular strain. through the years, the stress at the optic nerve can cause progressive and irreversible damage and permanent imaginative and prescient loss. note that an expanded intraocular stress, does not mean glaucoma, if no optic nerve damage is located. in this example, it’s miles known as ocular hypertonia.

Glaucoma, as a minimum within the initial degrees, offers no signs and symptoms. it’s far the primary cause for the excessive risk of this insidious disorder. in advanced degrees but aside from damages to the peripheral vision alteration starts within the relevant imaginative and prescient as nicely.

Predisposing factors:

  • Heredity (circle of relatives records)
  • Superior age (growing old)
  • Diabetes
  • Hypertension
  • Myopia
  • Black race
  • Long-term management of cortisone, especially domestically (eye drops)
  • Eye damage
  • Vascular sicknesses
  • Eye inflammations

Glaucoma, in the majority, stays undiagnosed, so it’s miles essential to perform an ophthalmologic checking out after age forty.

Corneal conditions

  • More

The cornea is the clear “window” of the attention inside the world. this anterior layer of tissue is the most refractive surface of the attention and it’s miles accountable for the appropriate focusing of the mild rays at the retina, which in flip interprets mild into optical stimulus.

The cornea is made out of the subsequent layers:

  • Epithelium
  • Bowman’s membrane
  • Stroma
  • Descemet membrane
  • Endothelium

Commonly the thickness of the cornea is between 450 and 620 microns. pachymetry is very vital data in a refractive take a look at when you consider that it’s miles a key criterion of choosing a technique in case of a refractive surgical treatment with laser (lasik, prk). any blurring or change in corneal curvature has an immediate effect at the exceptional of vision.

Corneal conditions:

Because the cornea is exposed (now not continuously included by the eyelids) it is simple to be injured or infected. for that reason trauma, infections, hereditary ailment is able to reason blurring, distortion or scarring in the cornea. whilst the cornea turns into cloudy, light can not bypass thru the attention and attain the retina. the end result is the vision discount (in extreme cases, blindness). the cornea has many superficial nerves ensuing in excessive ache in minimal injury. the existence of ordinary tear protects corneal drying and infections, hence the tear deficiency is able to causing issues inside the corneal layers.

There are numerous diseases and corneal dystrophies, the maximum essential are those under:

Keratoconus: a fairly common situation in which the cornea of the eye steadily takes a hard cone form and can motive extreme disturbance of the vision because of the introduction of irregular astigmatism

Peripapillary senile halo: it is the most common peripheral corneal clouding with the advent of lipid deposits. it is age-associated and it’s far determined in clearly every body over 80 years

Keratoglobus: a unprecedented circumstance which begins at birth. it’s miles characterised with the aid of thinning of the cornea at the ends. in a few instances precipitated rupture of the descemet membrane or even rupture of the entire cornea because of its fineness

Endothelial fuchs dystrophy (fuchs dystrophy): refers back to the swelling of the middle layer of the cornea because of the non-replacement of endothelial cells resulting in turbidity of sight
