Specialised eye examination <\/h3>\n<\/div>

FAQ<\/h1>\n<\/div>
\n
\n
\n\n<\/span>\n<\/span>\n<\/span>\nIs it possible to undergo the pre-surgery examination and laser eye surgery in one day?<\/a>\n<\/div>\n
\n
\n

We definitely <\/span>do not recommend<\/b> this at our clinic. As part of the specialised eye examination we also carry out the examination of the rear segment (vitreous humour, retina, optic nerve). To do so, we use eye drops that dilate the eye and thus the reactive dynamics of the pupil and its adaptability is distorted. This may complicate the registration of points on the iris which is essential for all types of tailor-made procedures. In addition, all eyedrops and any manipulation with the eye may disrupt the tear film of the eye. Ideally, we aim to carry out laser eye surgery once in a lifetime and so why take the extra unnecessary risk.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nIs it necessary for the pre-surgery eye examination to involve using eyedrops to dilate the eyes? <\/a>\n<\/div>\n
\n
\n

There exists a plethora of beliefs and discussions on this matter. The fact remains that a <\/span>thorough examination of the periphery of the retina is next to impossible without dilation.<\/b> Another irreplaceable examination is the examination of the refraction in the so-called cycloplegia (once the adaptability of the intraocular lens has been eliminated). Often, the readings between the manifest (measuring of the eye without prior preparations, whereby it is impossible to eliminate adaptation efforts \u2013 focusing) and the cycloplegic refraction (measurements once the eye has been dilated, where the result is without the effect of the adaptation of the pupil) are widely different.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nAt what age is it suitable to first undergo specialised eye examination in children? From what age onward do you examine children at your centre? <\/a>\n<\/div>\n
\n
\n

The very first eye examination in children is carried out <\/span>before leaving the maternity hospital<\/b>. It serves as a tool to eliminate hereditary pathological phenomena (cataracts, tumours). An indicative <\/span>eye test is carried on your child at your paediatrician before starting school<\/b>. Until this time, a child comes to a specialised ophthalmological centre only <\/span>in case of issues with vision<\/b> (increased tearing, repeat conjunctivitis, inflammation, lazy eyes, trauma and cases where the child overlooks objects or bumps into obstacles). The paediatric ophthalmologist decided the course of action.<\/span><\/p>\n

At our clinic, we carry out examinations in slightly <\/span>older children who are of an age to be<\/b> able to co-operate<\/b> with the person examining them. Usually, we examine children in cases where there is potential of a higher degree of a refractive error or where suspicions prevail of a corneal disease, for example keratoconus. The co-operation of the child during such an examination is absolutely necessary. Older children are also taught to apply the contact lenses.\u00a0\u00a0<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nHow often is it recommended to undergo regular preventive examination taking into consideration one\u2019s age? <\/a>\n<\/div>\n
\n
\n

If we leave out our minor patients here, <\/span>the frequency of examinations<\/b> depends on age and diagnosis<\/b>. Generally speaking, <\/span>for prevention purposes<\/b>, it is applicable that every person aged 40+ should undergo an eye examination <\/span>once a year<\/b>. This is the age of the onset of both, cataract and glaucoma as well as ailments of the retina. The sooner the disease is discovered, the easier it is to cure it. In addition, this is also the time when the so-called presbyopia (the natural ageing of the eyes) may start causing issues. Prescribed correction (reading glasses) often ends up solving issues unexplained until this point (headaches, dizziness).<\/span><\/p>\n

The frequency of your visits to your ophthalmologist in case of a refractive error depends on its development. <\/b>When the progression is fast, it could be as often as every 3\u20124 months. The same rules apply for patients with keratoconus \u2013 this is the only way that action may be taken in good time.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nWhen is it inevitably necessary to seek help from your ophthalmologist?<\/a>\n<\/div>\n
\n
\n

This applies in many cases. <\/span>In case of<\/b> trauma,<\/b> the patient must seek out his doctor <\/span>immediately<\/b>. A patient must waste no time in getting professional help also when experiencing loss of vision, sudden appearance of flashes of light or a grey curtain-like phenomenon moving across the field of vision. In such cases we recommend that you visit a larger clinic where they are likely to also have an emergency department.\u00a0\u00a0<\/span><\/p>\n

The situation is somewhat different where there are <\/span>eye infections <\/b>in question. Here, the 24-hour rule applies. It is possible to commence treatment using eye drops recommended by a pharmacist. Should the treatment not help within 24 hours, then it is advisable to visit an eye specialist and increase hygiene care at home (thorough washing of the hands, separate towels) so as to curb the spread of potential infection to the other members of the household. <\/span><\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n

\n
\n
<\/div>\n
\n
\n
\n\n<\/span>\n<\/span>\n<\/span>\nIs it possible to use my prescription for corrective glasses also for contact lenses?<\/a>\n<\/div>\n
\n
\n

Dioptres in glasses and in contact lenses do not correspond. <\/b>It is an example of using physical (optical) principles in practice. The contact lens is placed directly on the cornea, but the rear surface of the glass in your glasses is some 12 millimetres from the apex of the cornea. What more, different types and different manufacturers of contact lenses differ (for example for a glass used in glasses with \u22123 dioptres the corresponding contact lenses would be some 0.25 to 0.5 dioptres weaker.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nMust I refrain from using contact lenses before my specialised eye examination as well as prior to the surgery itself?<\/a>\n<\/div>\n
\n
\n

The main problem comes in where hard contact lenses are worn however, even soft contact lenses may enforce their shape onto the cornea. Lenses function in a similar manner as corrective teeth braces. When we carry out your examination, we <\/span>need to know the real curvature of your cornea<\/b> and this is why it is absolutely necessary to refrain from using contact lenses prior to the examination where your surgery is planned.<\/span><\/p>\n

Yet another negative influence is that the lens in your eye may also influence the thickness of your cornea and the condition of the upper most layer \u2013 the epithelium.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nFrom what age is it ok to wear contact lenses? <\/a>\n<\/div>\n
\n
\n

When using contact lenses, it is important to take into consideration a certain degree of risk of damaging your cornea. Such damage may arise through wrong manipulation, when using mechanically damaged contact lens, when a foreign body accidentally finds its way under your contact lens or into the conjunctival sac. Subsequently, there is also the <\/span>risk of contracting infection<\/b> which may lead to permanent damage. Similar risk is linked to \u201ctransferring\u201d your contact lenses or where hygiene is insufficient (hands, lens, container, solutions). As such, a person that wears contact lenses should be an <\/span>individual who is agile enough and mentally mature enough<\/b> to understand and be able to forego such risks. Judging such capabilities in children may be tricky, therefore, a high-quality co-operation between the child, the parent as well as the contactologist is essential.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nMust I remove all eye make-up before my specialised examination?<\/a>\n<\/div>\n
\n
\n

Yes, for hygienic as well as medical reasons. During a specialised eye examination, your eyelids are very likely to be manipulated with and as such, particles of your make-up may reach places within your eye where it is not advisable for such particles to reach (for example the conjunctival sac). <\/span>There exists a high risk of irritating the eye or contracting infection.<\/b> In addition, the greasy components of cosmetic products significantly affect the tear film of the eye and as such may distort the results of some of the specialised examinations. This in turn may negatively influence the actual outcome of the surgery. The same applies to the surgical procedure as well as the post-surgery period. During the post-surgery period, the pressure exerted on the eye when removing make-up would also be a problem.<\/span><\/p>\n<\/div>\n<\/div>\n<\/div>

\n
\n\n<\/span>\n<\/span>\n<\/span>\nWhat do the 20\/20, 6\/6, 1.0 vision classifications stand for?<\/a>\n<\/div>\n
\n
\n

For us to be able to compare the quality of eye sight in different patients and among different doctors as well as to facilitate and speed up this process, a <\/span>quality of vision scale<\/b> is used. Most commonly it states the result as a fraction or a real number.\u00a0<\/span><\/p>\n

Vision graded with the values of 6\/6, 20\/20 or 1.0 always stands for perfect, 100% vision. It basically means that at a distance of 6 metres a patient actually sees what he should be seeing at a distance of 6 metres (6 metres are equivalent to 20 feet and this is where the value 20\/20 comes from). A 50% vision is therefore graded as 6\/20, 20\/40 or 0.5. Thanks to modern laser methods (individualised procedures of the <\/span>iDesign <\/b>type) it is feasible, in many patients, to reach vision beyond the 20\/20 boundary. This means more than 100%!<\/span><\/p>\n<\/div>\n<\/div>\n<\/div><\/div>\n<\/div><\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
