Knowledge base – your guide to healthy vision

Knowledge base

The Vision Guide is a structured guide to knowledge about vision: from laser vision correction and lens surgery, through cataract and presbyopia, to symptoms of eye diseases and everyday prevention. Each topic leads to the main page on the subject and to the most-read articles.

Our content is written at the SwissLaser clinics in Warsaw and Kraków and reviewed by Dr. med. Victor Derhartunian, FEBO, FWCRS. It does not replace an eye examination – if symptoms have appeared suddenly, book an appointment.

Swollen Eyes

Swollen Eyes – Causes and Home Remedies

Swollen Eyes – At a Glance

  • Most common causes: allergies, conjunctivitis or stye, salt and alcohol, insufficient sleep, crying, hormonal changes; less commonly kidney, thyroid, and heart diseases.
  • Quick relief: cold compress for 10 minutes, elevated head during sleep, hydration, and less salt; for allergies – antihistamine.
  • Warning signs: swelling of one eye with pain, redness, fever, or worsening vision requires an urgent visit – it could be orbital cellulitis.
  • Recurrent swelling should be consulted with an ophthalmologist to check the eye surface and eyelids, especially when accompanied by dryness or burning.

Swollen eyes are a common ailment that can significantly impact quality of life and appearance. Although often underestimated, it can be a signal of various health problems – from mundane causes related to lifestyle to more serious conditions requiring medical intervention.

Eye Anatomy – How is the Human Eye Structured?

Eye Anatomy – In Brief

  • The eyeball is approximately 24 mm in diameter and has three layers: outer (cornea, sclera), vascular (iris, ciliary body, choroid), and inner – the retina.
  • Path of light: cornea – aqueous humor – pupil – lens – vitreous body – retina – optic nerve – visual cortex of the brain.
  • The macula is a small area of the retina responsible for sharp central vision, reading, and facial recognition.
  • Vision defects are an optics problem, not a retina problem: laser reshapes the cornea, and lens surgery replaces the internal lens.

The eye is one of the most fascinating and important organs of the human body, allowing us to experience the world through the sense of sight. Its complex structure resembles a precisely designed biological camera, where each element plays a crucial role in the process of vision. Understanding the architecture of the eye is essential for making informed decisions regarding vision correction and maintaining eye health throughout life.

What is Astigmatism - Symptoms and Treatment

Astigmatism – Symptoms and Treatment

Astigmatism Symptoms – In Brief

  • Typical symptoms: blurred or “stretched” vision at any distance, distorted lines, streaks and halos around lights at night, squinting, headaches, and fatigue after reading.
  • Cause: the cornea (less often the lens) is shaped like a rugby ball instead of a sphere, so light focuses at two points instead of one.
  • Diagnosis: refraction test and corneal topography, which rules out keratoconus; early detection in children is important, as uncorrected astigmatism can lead to amblyopia.
  • Correction: glasses or toric contact lenses only alleviate symptoms; permanent correction is provided by laser vision correction, phakic IOLs, or toric IOLs during cataract surgery.

Astigmatism is a common vision defect that affects millions worldwide, often accompanying other vision problems. Although it can significantly impact visual comfort and quality of life, modern medicine offers effective and safe methods for its correction. In this article, we provide comprehensive information on astigmatism – from its causes and symptoms to modern diagnostic and treatment methods available at our clinic.
