Taking the medical history is the starting point for all patients followed by a full eye examination. Prof. Findl will take note of your medical condition, any prior eye diseases and other diseases that may have an influence on your eye sight.
Within seconds, an approximate measurement of your prescription is made with an autorefractor. The results of these measurements will form the basis for later manual precise adjustment of your prescription. Your previous glasses will be measured using a lensometer. This device may also check the UV-protection of your sun glasses.
The precise refraction is performed using a set of corrective lenses. This procedure is done manually with a trial frame because Prof. Findl considers this method to be the most physiological and accurate in contrast to automated measurements. Afterwards, using the vision chart, visual acuity is measured.

The slit lamp is a microscope used to examine the eye. It provides a stereoscopic magnified view of the eye. Prof. Findl uses a precision model by Haag-Streit, the leading company for slitlamps based in Switzerland. The bright light of the slit lamp may cause some discomfort, but be assured that it is harmless for your eyes.

The average value of intraocular pressure in the healthy eye varies between 10- 22 mmHg. With patients over 40 years of age, measurement of intraocular pressure is a matter of routine. Applanation-tonometry is considered the most accurate technique of measurement. Since Prof. Findl uses unpreserved local anestetic eye drops, the usual stinging in the eyes is reduced significantly. Afterwards, you may experience a slightly numb feeling on the edges of your eye lids.
If the intraocular pressure is elevated, an extensive workup for possible glaucoma will follow.

Holding a lense in front of the eye, the inside of the back of the eye can be examined at the slit lamp. Retina and optic nerve can be assessed under high magnification. This procedure is of greatest importance in patients sufferng from diabetes mellitus, glaucoma, high blood pressure, AMD and other retinal problems.
In children, the retinal examination may be performed either with direct or indirect ophthalmoscopy.
In many cases, thorough retinal examination will necessitate dilatation of the pupil using eye drops which take about 20 -30 minutes to take full effect. During this time, you can have a seat and relax in our waiting area. The effect of the pupil dilating drops will wear off after a few hours but may temporarily blur your vision, especially during reading and driving. For this reason driving during the first few hours after retinal examination is not recommended. Prof. Findl uses the lates unpreserved and short acting dilating drops to keep the discomfort as minimal and short as possible.

In patients with an increased intraocular pressure and/or a suspicious appearing optic nerve, a visual field test is performed to rule out the diagnosis of glaucoma. The latest version of an automated visual field analyser by Humphrey-Zeiss is in use in Prof. Findl's practice. The print out of the visual field will then be discussed with you and stored for future reference.

In patients where a retinal tear or hole are suspected, especially in short sighted patients and patients reporting sudden onset of floaters, a special contact lense may be used to visualize the most peripheral part of the retina. This examination may be experienced as slightly uncomfortable, but is not harmful.

Retinoscopy, the refraction of the eye, can be assessed objectively and is especially useful in children.

To assess the stability of the tearfilm, yellow dye is applied. Under blue light, the time until the break up of the tear film is measured.
During the so called "Schirmer-test", small strips of filter paper are positioned just inside the lower lids to measure the the amount of tears present. After 5 minutes, the wetting of the filter strips should be at least 15 mm in length.

Since about 8% of the male population have some colour vision deficiency, Prof. Findl can test your colour vision if desired. To get an idea, try our online colour vision-test.
