Eye Examinations

Accurate diagnosis is the first and most crucial stage of cooperation between the patient and the doctor. It is important to perform it in a reputable clinic that has modern equipment and employs doctors who accurately interpret examination results.
Vision Screening from an Early Age
At SwissLaser, we use the Swiss Leonardo Da Vinci LDV Z4 femtosecond laser from Ziemer, a leading Swiss manufacturer of femtosecond lasers. The femtosecond laser is an infrared-emitting laser used for incising the cornea and creating a so-called “flap” – a corneal flap that is lifted and then closed again after the laser procedure.
Key advantages of this laser include its high frequency (MHz), low pulse energy (nJ), and small pulse area. Thanks to these unique properties, it has been possible to further enhance the quality and precision of corneal incisions. This modern technology has already been utilized in several million operations.
Regular Eye Examinations Save Your Vision
For adults, routine (i.e., PREVENTIVE) ophthalmological examinations should be performed at least every 2 years. After the age of 40, conditions such as cataracts, glaucoma, and macular degeneration (AMD) begin to develop. Initially, they may not present any symptoms, but if not diagnosed in time, they can lead to significant vision deterioration or even blindness. In such cases, immediate treatment or the selection of glasses/contact lenses is no longer an option; surgical solutions become necessary.

Standard Eye Examination for Corrective Glasses or Contact Lenses
We Distinguish OCT
A standard eye examination, commonly referred to as a computerized eye examination, is performed using an autorefractometer, a device used to measure the eye’s optical error (refractive error – commonly: vision defect). The principle of the autorefractometer’s operation involves painlessly and non-invasively directing an infrared light beam into the eye, and then analyzing the reflections of this beam from its structures. These reflections are processed by a computer processor, which generates data indicating the refractive error.
The measurement for each eye takes only a few seconds, and the patient only needs to look through a small opening where they see an image of a distant object. The examination result determines only the approximate optical correction (power of glasses or contact lenses) that can be applied. At this point, an ophthalmologist or optometrist steps in and, using tools other than a computer, determines the optimal spectacle correction (or contact lenses) for the individual.
Broad Diagnostic Capabilities of Modern Ophthalmology
Naturally, patients visit ophthalmologists not only to select glasses or contact lenses. They are also brought here by spontaneous eye diseases and systemic diseases, in the course of which, as one of the ailments (or, for example, a side effect of medication), vision disturbances and eye diseases appear.
It also happens that during a standard eye examination, the doctor discovers something concerning and implements further diagnostics. Finally, modern ophthalmology, which includes refractive surgery, offers surgical methods that not only significantly improve visual comfort in cases of large/complex refractive errors but also save vision when the only solution proves to be the implantation of an artificial lens. Patients therefore visit ophthalmology clinics to find out whether laser vision correction or artificial lens implantation is possible in their case.
When diagnostics more complex than a standard eye examination for corrective glasses or contact lenses are necessary, the specialist has the ability to perform a truly large number of maximally precise detailed examinations.
Diagnostic Examinations in Modern Ophthalmology
Badanie dna oka
Fundus examination (ophthalmoscopy, funduscopy) – in the diagnosis of systemic disorders, e.g., diabetes, atherosclerosis, arterial and intracranial hypertension, autoimmune diseases such as lupus or rheumatoid arthritis, and in the recognition of abnormalities in the structure and function of the retina, choroid, and optic nerve
Badanie tomograficzne nerwu wzrokowego
Optic nerve tomography (e.g., OCT or GDx or HRT) – in the diagnosis of glaucoma
Badanie OCT oka
OCT eye examination (Optical Coherence Tomography) – in the diagnosis of retinal diseases, AMD, diabetic maculopathy, before planned cataract removal and artificial lens implantation, in monitoring the course of glaucoma, in monitoring the condition of the cornea before and after laser vision correction procedures
Biometria oka
Ocular biometry in diagnostics before laser vision correction or artificial lens implantation
Biomikroskopia
Biomicroscopy (examination of the anterior segment of the eyeball with a slit lamp) – in the diagnosis of glaucoma
Gonioskopia
Gonioscopy (examination of the drainage angle) – in the diagnosis of glaucoma
Keratometria
Keratometry (ophthalmometry, corneal topography) – in the diagnosis of refractive errors and astigmatism (necessity of selecting spectacle lenses/contact lenses), before (and after) planned laser vision correction procedures/artificial lens implantation, in the diagnosis of certain corneal diseases
Pachymetria
Pachymetry – in the diagnosis of glaucoma and ocular hypertension, before surgical procedures, including laser procedures, on the cornea, as well as in the diagnosis of keratoconus and other corneal conditions
Perymetria
Perimetry (visual field examination) – in the diagnosis of glaucoma
Tonometria
Tonometry (IOP – intraocular pressure measurement) – in diagnostics before deciding on laser vision correction
Topografia rogówki
Corneal topography (computerized/digital or manual keratometry) – in diagnostics before laser vision correction and before selecting implantable artificial lenses, which are used in the treatment of myopia, hyperopia, astigmatism, and cataracts, in the diagnosis of keratoconus
Example “Bundle of Examinations” in Glaucoma Diagnostics
Set of Basic Examinations
- examination of refractive error and visual acuity,
- examination of the anterior segment of the eyeball with a slit
lamp (biomicroscopy), - intraocular pressure measurement (tonometry),
- fundus examination after pupil dilation.
Set of Additional Examinations
- visual field examination (perimetry),
- gonioscopy (examination of the drainage angle),
- corneal thickness measurement (pachymetry),
- optic nerve tomography (e.g., OCT or
GDx or HRT), - anterior segment imaging (e.g., OCT or
UBM).
Example “Examination Package” in Cataract Diagnostics
For an experienced doctor, diagnosing cataracts only requires examining the clouded lens with dilated pupils. Examinations preceding cataract surgery include:
- autorefractometry
- biometry
- fundus examination
- macular OCT examination
Example “Examination Package” preceding surgical intervention in the eye (eye surgery)
- corneal topography/corneal tomography (3D),
- pupil width measurement,
- intraocular pressure measurement (IOP) with corneal hysteresis,
- autorefraction,
- subjective refraction,
- binocular vision examination,
- optical biometry,
- optical coherence tomography (OCT) / macula and optic nerve,
- posterior segment imaging,
- endothelial cell density measurement,
- ophthalmological examination with a biomicroscope.
