PRK Surgery and Post-Operative Care
PRK (Photorefractive Keratectomy) surgery is another surgical method for correcting refractive errors of the eye, such as nearsightedness, farsightedness, and astigmatism. It's similar to LASIK, but instead of creating a flap in the cornea, a thin layer of the cornea's surface is removed, and then a laser is applied to the underlying tissue.
 
Benefits of PRK Surgery
Suitable for thin corneas: One of the most significant advantages of PRK is its suitability for individuals with thinner corneas.
Lower risk of flap-related complications: Since PRK doesn't involve creating a flap, the risk of complications associated with flap displacement is reduced.
 
Post-PRK Surgery Care
Post-PRK surgery care is generally similar to post-LASIK care. However, due to the removal of the surface layer of the cornea, the healing period for PRK may be slightly longer. Some of the most important post-PRK surgery care points include:
 
Using eye drops: Regular use of eye drops prescribed by your doctor is crucial to relieve pain, reduce inflammation, and prevent infection.
Avoiding rubbing your eyes: Avoid rubbing your eyes for a few days after surgery to prevent damage to the cornea.
Wearing sunglasses: Wearing sunglasses with full UV protection is essential to shield your eyes from sunlight.
Avoiding strenuous activities: Avoid strenuous activities such as contact sports, swimming, and lifting heavy objects for a few days.
Regular follow-up visits to the doctor: Regular follow-up visits to your doctor are necessary to monitor your progress and ensure there are no complications.
 
Side Effects of PRK Surgery
Side effects of PRK surgery are similar to LASIK and may include dry eyes, halos around lights, light sensitivity, infection, and reduced night vision. However, due to the removal of the surface layer of the cornea, the healing period and discomfort after PRK surgery may be slightly longer.
Choosing between LASIK and PRK depends on various factors such as corneal thickness, the type of refractive error, lifestyle, and your doctor's recommendation.
 
 
World Hepatitis Day 2024

A Silent Threat, It Is Time to Action

A Silent Threat, It's Time to Action - World Hepatitis Day 2024

The World Health Organization has designated July 28th as World Hepatitis Day to raise awareness about this disease, encourage vaccination, promote early diagnosis, and facilitate effective treatment for hepatitis. Early detection of hepatitis is crucial as prompt treatment can prevent the disease from progressing to cirrhosis or liver cancer.

The World Health Organization (WHO) has designated July 28th as World Hepatitis Day to raise global awareness about hepatitis, a group of infectious liver diseases. The day aims to encourage vaccination, promote early diagnosis, and facilitate effective treatment.
Early detection of hepatitis is crucial as prompt treatment can prevent the disease from progressing to cirrhosis or liver cancer. The ultimate goal is to reduce new hepatitis cases by 90% and hepatitis-related deaths by 65% by 2030. Reflecting this ambition, the WHO's slogan for 2024 is "It's time to action."
 
What is Hepatitis?
Hepatitis is the inflammation of the liver. This inflammation can be caused by viruses, chemicals, medications, or certain autoimmune diseases. The most common types of hepatitis are viral hepatitis caused by the hepatitis A, B, and C viruses.
 
Consequences of Hepatitis
The widespread prevalence of hepatitis can impose a significant economic burden on governments and communities. The high costs associated with treatment and the decreased productivity of the workforce can negatively impact a country's economic growth. Furthermore, individuals living with hepatitis may face long-term health problems and a reduced quality of life.
 
Transmission of Hepatitis
Hepatitis A: Transmitted through contaminated food or water, or direct contact with an infected person.
Hepatitis B: Transmitted through contact with infected blood or bodily fluids, such as unprotected sex or sharing needles.
Hepatitis C: Primarily transmitted through contact with infected blood, such as injecting drugs with contaminated needles or receiving contaminated blood products.
 
Symptoms of Hepatitis
While symptoms can vary, common signs of hepatitis include:
Extreme fatigue
Loss of appetite
Nausea and vomiting
Abdominal pain
Jaundice (yellowing of the skin and eyes)
Dark urine
Pale stools
 
Prevention and Treatment
To combat hepatitis:
Vaccination: Effective vaccines are available for hepatitis A and B.
Testing: Regular testing for early detection.
Safe behaviors: Practicing good hygiene, using condoms, and avoiding sharing needles.
Education: Raising public awareness.
Support: Providing support for those living with hepatitis.
Treatment for hepatitis depends on the specific virus and stage of the disease. While some cases resolve on their own, antiviral medications are available for hepatitis B and C.
 
Conclusion
Despite the challenges, the future of the fight against hepatitis is promising. Advancements in diagnosis, treatment, the development of new vaccines, and increased public awareness are all contributing to improving the lives of those affected by hepatitis. With global cooperation and investment, we can significantly reduce the burden of hepatitis by 2030.
