London Eye Specialist: Preventing and Treating Seasonal Eye Allergy

Seasonal eye allergies are commonly caused by allergens such as pollen, grass, or weeds. When these allergens come in contact with your eyes, they bind themselves to mast cells full of antibodies. In response, your immune system releases histamine and other chemicals to combat the foreign invader. This causes tiny blood vessels in the eyes to leak, causing itchiness, redness, and excess production of tears. As you can imagine, these can be bothersome.
Preventing seasonal eye allergies
It’s close to impossible to eradicate seasonal allergy symptoms completely, because allergies are part of your body’s make-up regarding the way it handles foreign particles. That’s why you’ll observe that you have specific allergies, while others don’t have them, or react to different sets of allergens altogether, such as latex or pet dander. It is your body’s specific reaction to seasonal allergens that produces the symptoms. Read more on this article.

London Eye Clinic—Are You at Risk of Age-Related Macular Degeneration?

NHS Choices named age-related macular degeneration (AMD) as the number one cause of vision loss in the UK. Experts predict that almost 700,000 people will have late stage AMD by 2020. Do you know the signs? Are you at risk? Your London eye clinic wants to help you ensure that you are well informed about the condition so you can take necessary precautions.
What is age-related macular degeneration?
The ‘central vision’ is what allows you to focus your vision so you can see objects clearly. When you vision has the capacity to focus, you can do common daily tasks such as reading, writing, identifying faces, and watching a movie with ease. AMD is a disease that gradually destroys this ability to focus. It attacks the macula, the part of the retina that allows a person to see in full detail. Read more on this article.

London Eye Doctor Answers 4 FAQs about Phototherapeutic Keratectomy

Phototherapeutic keratectomy (PTK) is a type of eye surgery technology used by a London eye doctor to treat diseases and scars on the corneal surface. A common misconception about PTK is that it’s used to improve vision, but this is not the case. Those who want to address eye scars and diseases and address a vision problem at the same time may also need to undergo a photorefractive keratectomy procedure. 
What makes PTK different from PRK and LASIK?
PTK focuses more on medical benefits and less on improving eyesight. The problems that ETK is meant to solve are associated with diseases that affect the cornea, whereas PRK and LASIK are more related to the eye’s refractive issues. Examples of diseases and conditions that PTK can treat include corneal dystrophy, epithelial erosion syndrome, and scarring of the cornea. PRK and LASIK can treat and astigmatism presbyopia. Read more from this blog:

Two Birds with One Stone-Addressing Astigmatism with Cataracts Surgery

Cataracts and astigmatism are two common vision problems, and sometimes they can occur together. A cataract is a condition wherein protein in the eye lens clump and cloud together to form a blurry spot in the eye. Meanwhile astigmatism is a refractive error caused by an eye not being completely round. It is actually possible for an eye doctor to address both conditions in a single surgery.
How can cataract surgery fix astigmatism?
During cataracts surgery, the doctor can alter the shape of the cornea in one of two ways: by making a tiny incision in the cornea and make it rounder, or by placing a football-shaped lens on the cornea to correct the individual’s vision. Both of these options can neutralise a misshapen cornea and minimise if not eliminate the astigmatism symptoms.
If astigmatism persists after cataract surgery, an eye doctor can perform additional surgical procedures after the eye fully recovers from the surgery. These include LASIK and phototherapeutic keratectomy. Read more from this blog:
