Frequently Asked Questions (FAQ) :
1. Are halos around lights always a cause for concern?
Not necessarily. While they can be caused by simple refractive errors, they may also be a sign of a more serious condition. A comprehensive eye exam is the best way to determine the cause.
2. Can halos be treated without surgery?
Yes, if the cause is something like refractive errors or dry eye, non-surgical treatments like glasses or eye drops can help. Surgery may be necessary for conditions like cataracts or glaucoma.
3. Will my halos go away after LASIK?
Halos are a common temporary side effect after LASIK, but they usually fade within a few weeks or months. If halos persist, further evaluation may be required.
About Halos Around Lights
Halos are bright circles or rings that appear around lights, especially at night or in dim lighting. They can make it difficult to drive or see clearly in low light conditions and may indicate an issue with your eyes. Although halos around lights are often harmless, they can sometimes be a symptom of an eye condition that requires medical attention.
Causes of Halos Around Lights
Halos can be caused by several factors, including:
- Refractive Errors: Conditions like nearsightedness, farsightedness, or astigmatism can cause halos due to improper focusing of light on the retina.
- Cataracts: A clouding of the lens of the eye, cataracts can scatter light and cause halos, especially at night.
- Glaucoma: Increased eye pressure can lead to damage to the optic nerve, which may result in halos.
- Dry Eye Syndrome: A lack of adequate tears can affect the way light enters the eye, causing halos.
- LASIK or Other Eye Surgery: Post-surgery visual disturbances like halos are common but usually temporary.
- Corneal Edema: Swelling of the cornea due to injury or disease can cause halos.
- Contact Lens Issues: Wearing dirty or improperly fitted contact lenses can lead to visual disturbances like halos.
Types of Halos
There are a few different types of halos that patients may experience:
- White Halos: Most commonly associated with refractive errors or cataracts.
- Colored Halos: May indicate more serious conditions like glaucoma.
- Starburst Halos: These may occur after LASIK surgery or in cases of astigmatism.
Symptoms of Halos Around Lights
If you’re experiencing halos, you might notice the following:
- Bright rings or halos around streetlights, headlights, or other sources of light.
- Difficulty driving at night due to glare and light sensitivity.
- Blurry or foggy vision, especially in dim light.
- Distorted vision when looking at light sources.
Diagnosis of Halos
Dr. Suraj Munjal and his team will perform a comprehensive eye exam to determine the cause of your halos. The diagnostic process may include:
- Visual Acuity Test: To check your overall vision.
- Slit-Lamp Exam: A closer look at the structures of your eye, including the cornea, lens, and retina.
- Tonometry: Measures the pressure in your eye to rule out glaucoma.
- Pupil Dilation: To get a better view of the retina and optic nerve.
- Corneal Topography: To map the shape of your cornea, which helps in diagnosing astigmatism or keratoconus.
Treatment for Halos Around Lights
The treatment for halos depends on the underlying cause:
- Prescription Glasses or Contacts: Correcting refractive errors can often reduce halos.
- Cataract Surgery: If cataracts are the cause, surgery to replace the cloudy lens can eliminate halos.
- Glaucoma Treatment: Managing eye pressure with medications or surgery can reduce halos.
- Dry Eye Treatment: Eye drops, ointments, or treatments like punctal plugs can help manage dry eyes and reduce halos.
- Corneal Treatments: If the problem lies with your cornea, specialized contact lenses or surgery may be necessary.
Cost of Treatment and Stay in India
The cost of treatment for halos around lights varies depending on the cause and the treatment required. On average:
- Cataract Surgery: Starts at around $1,500 per eye.
