Recommendations for appointment

Our patients are subject to several studies for a complete ophthalmologic evaluation; so we recommend following these guidelines:

  • Your visit will be scheduled in advance in the form of appointmens, which can be booked by different means:
    Phone (506) 2224-6561 or (506) 2224-9322.
    Through fax (506) 2234-6798
    Via text message: 8355-4270
    E-mail: clinicadeojos07@ice.co.cr
  • Your examination includes pupil dilation, this will cause blurred for several hours, so it is advisable to be accompanied, or bring sunglasses. Your examination includes review of previous segment (assessment of status of cornea, conjunctiva and lens) and Eyeground (assessment of retina, macula and optic nerve).
  • Eyestrain to rule out glaucoma cases will be assessed.
  • You will need to bring your previous glasses.
  • If you have previous diagnostic tests such as visual fields, OCT, HRT, corneal topographies, referrals from other doctors, angiograms or photographs, it is advisable to present them to the specialist the day of the consultation.
  • If you are a contact lenses user, must discontinue the use of them at least 24 hours prior to your appointment.
  • If you are a senior citizen, must be accompanied by a family member or friend.

Application of ophthalmic treatment

Right way to apply your eye drops:
  • Wash hands thoroughly
  • Move your head back and look up
  • Using the fingertips, move down the eyelid
  • Use eye drops (should not exceed the number prescribed by your doctor) avoiding the tip of the bottle touching your eye(s)
  • Keep your eyes closed for at least 30 seconds
If further treatment should be applied such as drops, wait at least 5 minutes
Si debe aplicar otro tratamiento adicional en forma de gotas, espere al menos 5 minutos.

How to clean contact lenses?

Is it okay to clean my contact lenses with tap water?

It is not; because tap water may contain the microorganism Acanthamoeba, which causes a serious infection of the cornea.

Recommendations:
  • To clean your lenses should always use a special solution that is acquired in optical shops, pharmacies or supermarkets.
  • Before changing, cleaning or removing contact lenses wash your hands thoroughly.
  • Every day should use new solution, ie, never reuse the solution the day before.

Full assessment of your eyes

The assessment takes less than 30 minutes, is painless and can save your sight!

Includes:

  • Visual acuity test
  • Exploration of the upper segment
  • Taking intraocular pressure
  • Eyeground Examination

Recommendations for surgery

Before surgery
  • If you are a user of contact lenses, you should remove them 48 hours before surgery ICL, and a month earlier if laser surgery.
  • If you are a contact lenses user, also you should remove them before surgery Lasik (or refractive surgery).
  • Two days before surgery, a prophylactic treatment will be sent with anti-inflammatory and antibiotics medication, as directed by your doctor.
  • Analgesics before surgery will be sent.
  • Do not use any makeup.
  • You should wash your face with mild soap.
  • You can make a light breakfast.
  • The day of surgery, wear a shirt or a blouse with buttons.
After surgery
  • Apply drops as directed by your doctor.
  • No stooping, no weight lifting or scratching the eye.
  • If there is pain after surgery, you will be sent an analgesic as recommended by the doctor.
  • If pain persists please contact the clinic immediately.

Sleeping with contact lenses

Is it OK to sleep with contact lenses?

No, for several reasons:

  • During the hours of sleep we deprive oxygen to the cornea
  • We may suffer eye irritation
  • Left lenses may cause corneal infection known as bacterial keratitis

Bathing with contact lenses

Is it correct showering or swimming using contact lenses? 

It is not; tap water or swimming pools, among other sources, may contain a microorganism called Acanthamoeba which causes a serious infection.

The treatment Acanthamoeba is long and, despite this, can cause blindness.

Complementary studies

O.R.A.

The O.R.A. (Ocular Response Analyzer) is a revolutionary instrument designed to measure intraocular pressure and, simultaneously, the biomechanical properties of the cornea by a simple and quick test.
This instrument has a new alignment system that makes the pressure test is reliable and accurate, providing excellent results.

It also works through a process of bi-directional dynamic flattening that, aside from taking eye pressure, provides new information on previously unknown terms: Hysteresis Corneal and Corneal Resistance Factor.

All these factors are especially important in cases of refractive surgery, keratoconus and glaucoma, among other diseases. This modern instrument also provides the ability to keep track of all shots of the patient, including his presentation at statistical graphs.

Refraction

Refraction is known as the procedure used to measure optical defects of the eye and simultaneously determine the correction needed.

The four main refractive errors are: Myopia, hyperopia, astigmatism and presbyopia. They can cause blurred vision at different distances as well as symptoms such as headache, fatigue and sleep, among others. In order to handle these defects, we find several options, which include eyeglasses and contact lenses, mainly.

In addition, the refraction is essential for cases of refractive surgery or LASIK. Within a refractive examination a series of additional tests are made, they have to do with the evaluation of the oculomotor system and muscular, binocular vision, color vision and eye deviations, among others.

Non-mydriatic retinal camera

Our clinic has a camera that allows you to digitally capture and store images of retina safely, so that maintains a database of all visits of our patients over time.

Such studies are particularly important to patients with hypertension, diabetes mellitus, glaucoma and retinitis pigmentosa, for which periodic checks are necessary and require proper monitoring of your retina, to avoid future complications.

Thanks to this useful tool, the practitioner and the patient will notice if there have been significant changes, this in a graphical manner that allows evacuate any doubt over the previous state of the retina.

Another advantage of this camera is that it is not necessary to use pupil dilating drops to conduct the study. Nor does the application of any intravenous contrast, unlike other similar studies, which makes the most practical and simple test is necessary.
Our patients get copies of photographs, either printed or digital, for their own control or to serve as a study by other specialists such as endocrinologists, internists and rheumatologists.

Visual fields

Also known as perimetry, it is a test to measure visual function in a topographic location of a particular field of vision.

The field, itself, is the portion of the outer or peripheral environment that can be detected at the same time we are making a central fixation on an object.

It is a relatively simple, short test and requires no special preparation.

It is recommended for all cases of glaucoma, since it is one of the tests of choice for the diagnosis and control of this disease. Neurological disorders, treatments for rheumatic diseases, diabetes mellitus, among others, are also causes for this test.

Pentacam

So far, the Pentacam is the most specialized equipment, used on the exploration of the anterior segment of the eye. A rotating chamber is working under Scheimpflug system, which allows more precise and clear shots from all the anterior segment of the eyeball, which runs from the front of the cornea to the lens rear face.

It consists of a short examination, without any difficulty, with an also short examination time and will provides immediate results.

Also, turns out to be a basic test for cases of refractive surgery with excimer laser, surgery of cataract surgery with lens ICL surgeries corneal rings, adaptation of contact lenses, diagnosis of corneal dystrophies, among others, because it provides detailed information on:

  • Topography of the anterior and posterior corneal layers and elevation maps thereof
  • corneal thickness across its entire surface -Paquimetry-
  • Full Three-dimensional analysis of the anterior segment
  • Lens density -in cataract cases-
  • Anterior segment tomography
  • Calculation of intraocular lenses and contact lenses in special cases
Measurement of Intraocular Lenses

Procedure used for the election of the lens to be implanted during cataract surgery or a Phacorefractive.

The method consists of a Biometry in which the axial length of the eyeball is measured. Applying this result plus the keratometric measurements of the patient -measurement the corneal refractive power-   the biometric rule applies a series of established formulas resulting on the exact power needed of lens to be implanted.

Other ocular factors taken into account are:

  • Patient refractive previous state
  • Current status of the patient refractive cataract effect
  • Depth of the anterior chamber
  • General health of the eyeball
High Definition Optical Coherent Tomography

Optical Coherent Tomography is a diagnostic test where a structural virtual reconstruction of the macula (central portion of the retina) and the optic nerve is performed; It is occasionally called a “virtual biopsy”.

In our clinic we have a high-definition OCT, very useful in the diagnosis of many diseases such as macular degeneration related to age, macular holes, epiretinal membranes, central serous chorioretinopathy and diabetic macular edema or secondary.
