Retina & Vitreous Retina & Vitreous Vitreo-retinal diseases are conditions that affect structures inside the eye called the vitreous and the retina. The vitreous is the clear gel that fill the space between the lens and the retina. Retina is the light-sensitive layer in the back of the eye which forms image and transmit it to the brain through optic nerve. Vitreo-Retina Services You should see a Vitreo-Retina specialist if you have any of the following symptoms or you have been diagnosed with a vitreo-retinal condition during your routine eye examination. Symptoms can be any of the following: If you see flashes or sparks of light If you see floaters in the field of your vision Shadows or dimness in the peripheral vision Sudden loss of vision Difficulty in night vision Distortion of words while reading Blurring of central vision. Expertise in treating conditions of Vitreo-Retina Vitreo-retinal diseases are varied and may require different type of treatments. Other than the oral therapy and eye drops, such patients often require laser therapy, intravitreal injections in th eye or an eye surgery. Let’s discuss a few common ones: Diabetic Retinopathy: In patients of diabetes, abnormal blood vessels develop inside the eye which have tendency to bleed. Also, the blood supply to the eye is not enough in these patients leading to the release of a chemical called VEGF. Such patients require laser therapy to destroy those abnormal vessels and intravitreal injections to tackle the chemical VEGF. Age related macular degeneration: This condition involves the central portion of retina called the macula. This disease happens in old age. It can have a dry or wet form. Dry form has drusens and with atrophic changes, you might lose central vision. The wet form happens when blood vessels grow from underneath the macula. This condition is treatable with intravitreal injections. Retinal detachment: This is an urgent situation. Warning signs of retinal detachment may include flashes, floaters or sudden blurring of vision. It requires surgery as early as possible. Macular hole: In this condition, a hole develops in the centre of macula. This is the position where a normal person’s vision is the sharpest. In patients with macular hole, the central vision is affected. A macular hole can be successfully treated with surgery. Retina Lab at HOUSE OF VISION has state of the art diagnostic Imaging systems Spectral domain Optical Coherence tomography: Cross sectional images of the retina. OCT Angiography: This is a non-invasive dyeless angiography of the retina. Fundus photograph: 200 degrees of the retina can be easily visualised. Procedures and surgical treatment Intravitreal Anti-VEGF injections : These are required when there is swelling in the macula and in diseases of the blood vessels of the eye such as Diabetic retinopathy, Age related macular degeneration or vein occlusion. Laser therapy : Single spot and the latest multi-spot laser systems are used to treat conditions of retina. Multi-spot laser system allows faster completion of laser and causes less discomfort to the patient. Scleral buckling: For the treatment of retinal detachment. 3-D Micro-incision Vitreo-Retinal Surgery (3D-MIVS) : This allows for detailed and precise view of the retina. Retinal detachment, macular hole, diabetic vitrectomies and other complex surgeries are done under this futuristic surgical set up.

DRY EYE SYNDROME What is Dry Eye Syndrome? Dry Eye Syndrome (also called dry eye disease) happens when your eyes don’t produce enough tears or the tears evaporate too quickly. This can lead to discomfort, blurry vision, and even damage to the surface of the eye if left untreated. Common Symptoms Stinging, burning, or scratchy feeling in the eyes Redness Blurred or fluctuating vision Feeling like something is in your eye (foreign body sensation) Excessive tearing (a reflex to dryness) Sensitivity to light Difficulty wearing contact lenses Causes of Dry Eye Aging (especially post-menopause) Long screen time without blinking Environmental factors (wind, dry air, air conditioning) Certain medications (antihistamines, antidepressants, blood pressure meds) Medical conditions (e.g., rheumatoid arthritis, Sjögren’s syndrome) LASIK or other eye surgeries Treatment Options 1. Artificial Tears (Lubricating Eye Drops) Over-the-counter Use regularly (even when your eyes feel fine) Preservative-free drops are best for frequent use 2. Prescription Eye Drops Cyclosporine or Lifitegrast to reduce inflammation Corticosteroid drops (short-term use) for severe dry eye disease. 3. Lifestyle & Home Remedies Blink often, especially when using screens Use a humidifier Wear wraparound glasses outdoors Stay hydrated Apply warm compresses to the eyes 4. Punctal Plugs Tiny devices inserted into tear ducts to help retain moisture on the eye surface 5. Omega-3 Fatty Acids Found in fish oil or flaxseed oil; may help improve tear quality 6. Other Advanced Treatments Intense Pulsed Light (IPL) therapy Meibomian gland expression (clearing blocked oil glands) 📝 Tips for Managing Dry Eyes ✅ Follow your doctor’s treatment plan ✅ Avoid smoke and windy environments ✅ Take frequent breaks during screen time. Follow 20:20:20 rule (take breaks every 20 minutes & look 20 feet away for 20 seconds) ✅ Avoid over-the-counter redness-relieving drops (they can worsen dryness) ✅ Don’t ignore symptoms—early treatment prevents complications

LASIK & Refractive surgeries LASIK and Spectacle removal surgeries At House of Vision, we offer a wide range of spectacle removal procedures including Contoura LASIK, Trans-PRK, PRK and ICL procedures. We provide safe and effective ways for spectacle removal, which are approved by FDA. Before taking up the patients for the surgery, a detailed workup is performed to ensure that they are suitable for the procedure with the help of relevant tests. In the patients not suitable for LASIK laser, alternative options like ICL is advised. Depending on the individual needs, a decision is made for surgery after discussing in depth with patients: Standard LASIK: A flap is created in the cornea, and the underlying tissue is reshaped using an excimer laser. Contoura Vision: An advanced topography-guided LASIK procedure that enhances vision quality by correcting corneal irregularities. PRK (Photorefractive Keratectomy): A surface-based laser eye surgery that reshapes the cornea without creating a flap, ideal for thin corneas. ICL (Implantable Collamer Lens): A biocompatible, reversible lens implanted inside the eye to correct high refractive errors without altering the cornea. Are you eligible for LASIK? The ideal candidates for LASIK operation and other refractive surgeries include Individuals aged 18 or older with a stable vision prescription for at least one year. Patients should not be pregnant, lactating, or on birth control. Patients with healthy corneas and no significant eye conditions like glaucoma or cataracts. LASIK is safe for the eligible individuals! Quick and Painless: The procedure is performed under local anesthesia and takes a maximum of 10–15 minutes per eye. Rapid Recovery: You can resume normal activities in a day or two. Long-Term Results: LASIK offers permanent correction for refractive errors, although natural aging may affect vision over time. Improved Quality of Life: You are no more dependent on your glasses. Side Effects of LASIK Eye Surgery While LASIK surgery is generally safe, it’s important to be aware of potential risks and side effects : Temporary Dry Eyes: Many patients experience dryness, which is manageable with lubricating drops. Halos and Glare: Some individuals notice halos around lights, especially at night, during the initial recovery phase. Fluctuating Vision: Vision may vary slightly for a few weeks as the eyes heal. Rare Complications: Issues like infections or flap-related problems are extremely rare when performed by skilled surgeons. You need proper aftercare & precautions Proper aftercare is crucial for a smooth recovery and long-lasting results: Avoid Rubbing Your Eyes: To prevent dislodging the corneal flap. Use Prescribed Eye Drops: You must put your eyedrops as advised, for quick recovery. Protect Your Eyes: Wear sunglasses outdoors to shield against UV rays and dust. Limit Screen Time: Minimize screen exposure during the first few days to avoid strain. Regular check-ups ensure that your eyes are healing right.
