    What is astigmatism?

    Astigmatism is a refractive error caused by an irregular shaping of the cornea (mismatched curves with different radius of curvature on the main axes). This causes light to be dispersed to several points of the retina instead of focusing on one point.

    Symptoms of astigmatism

    Symptoms of astigmatism include blurry or hazy vision at any distance, distorted vision, visual fatigue, headaches, eye discomfort and irritation. Patients that suffer astigmatism tend to squint to see more clearly.

    Types of astigmatism

    The following types of astigmatism can be detected in patients:

    Simple astigmatism

    It only appears on one meridian. One axis is focused on the retina while the other axis focuses in front of the retina or behind it.

    Compound astigmatism

    It affects one meridian and is associated with myopia or hyperopia. Both axes focus before or behind the retina

    Mixed astigmatism

    Light rays come to two focal points, one of which is before the retina (myopic) and the other of which is behind the retina (hyperopic).

    HOW IS
    ASTIGMATISM
    CORRECTED?

    Astigmatism is usually corrected with eyeglasses or contact lenses. Patients who do not wish to rely on optical correction may choose to undergo refractive surgery.

    Different surgery methods are available for the correction of astigmatism. A personalised monitoring of patients is required to adapt a given treatment to the characteristics of the eye.

    LASER
    PROCEDURES

    • LASIK – Laser-Assisted in Situ Keratomileusis
    • PRK/LASEK – Photorefractive Keratectomy
    • ReLEx SMILE – Small-Incision Lenticule Extraction

    In cases where Excimer Laser Surgery is carried out it is possible to use a customised Wavefront TM guided system which reduces the induction of High Order Aberrations and grants a high quality vision.

    INTRAOCULAR
    PROCEDURES

    Intraocular lens implants represent a possibility to correct astigmatism in patients that do not meet the criteria for laser surgery (thin cornea, corneal trauma). Depending on eye condition and characteristics intraocular lenses may be:

    • Phakic intraocular lenses
      • Angle-fixated anterior chamber phasic intraocular lenses
      • Iris-fixated anterior chamber phakic intraocular lenses
      • Posterior Chamber Intraocular Lenses
    • Pseudophakic intraocular lens

    FREQUENTLY
    ASKED QUESTION

    Select any of the following FAQs from our patients and check the answers. If your doubts are nor solved please use the contact form below to get in touch with us.

    When can I undergo surgery to correct myopia/hyperopia?

    Refractive errors (myopia, hyperopia, astigmatism) can only be corrected when the patient’s prescription is stabilised, which occurs around the age of 20.

    Can I be operated if I also suffer from astigmatism, aside from myopia/hyperopia?

    Yes, any of the procedures currently used (laser and lens implants) allow the simultaneous correction of both errors.

    What happens if my eyes move during the laser surgery procedure?

    It is important that the eye remains as stable as possible during surgery, therefore patients are placed in a semi-recumbent position with their eyes fixed on a red light on the  Excimer Laser machine.

    A safety device called eye tracker compensates slight involuntary eye movements following up the eye at milliseconds intervals and adjusting the direction of laser pulses. In case of sudden movements the safety system fully stops the treatment.

    How long does laser surgery last?

    It is a quick procedure. Patients remain in the surgery room for 15-20 minutes as average. Just a few seconds of that time are used for the application of the Excimer Laser. The remaining time is used to prepare the patient’s eye for surgery.

    Is laser surgery painful?

    Refractive surgery procedures are carried out using topical (local) anaesthetics (eye drops). Patients do not experience any pain during the operation.

    How will the post-operative/recovery period be?

    LASIK and PRK  procedures have very simple post-operative processes which require only eyedrops and artificial tears. After surgery it is recommended to rest at least for 24 hours. Most work activities can be resumed after 48 hours. Patients must wait at least a week to resume any sport activity.

    I have a very high prescription. Can I undergo refractive surgery?

    During pre-surgery assessment tests, our medical staff will examine the condition of the cornea, namely corneal width and post-operative methods. Laser treatment reshapes corneal tissue. If the cornea does not meet specific safety criteria, intraocular surgery (which does not modify ocular structure) may be considered.
