In the United States, intraocular lens (IOL) models used for cataract surgery must meet the applicable regulatory requirements for that market. Established international manufacturers offer monofocal, toric, multifocal and extended-depth-of-focus (EDOF) lens designs. Availability and regulatory status vary by specific lens model and country. At Thakur Eye Hospital, IOL selection is based on eye measurements, visual requirements, lifestyle and clinical suitability.
Cataract surgery is performed and controlled by an ophthalmic surgeon. Femtosecond laser-assisted cataract surgery (FLACS) can automate selected steps, such as certain corneal incisions, opening the lens capsule and fragmenting the cloudy lens, but it does not replace the surgeon. Conventional phacoemulsification is also an established and widely used technique. The appropriate approach depends on the individual eye and the surgeon’s clinical assessment.
Cataract surgery may be covered under many health-insurance policies, but eligibility, waiting periods, room or procedure limits, lens-category coverage, co-payments and other conditions vary between insurers and individual policies. Patients should confirm the applicable terms with their insurer or third-party administrator before surgery.
There is no single injection that is appropriate for every patient with diabetic retinopathy or diabetic macular oedema. Depending on the retinal findings and clinical situation, anti-VEGF medicines may include ranibizumab products such as Accentrix or Razumab, bevacizumab (Avastin, commonly used off-label in ophthalmology where clinically appropriate), aflibercept (Eylea) or faricimab (Vabysmo). Steroid-based treatments such as dexamethasone implant (Ozurdex) or triamcinolone may be considered in selected cases. The retina specialist selects the medicine and treatment schedule after examining the patient and considering OCT or retinal findings, previous response, other eye conditions, systemic health, treatment frequency, safety and cost.
Retinal detachment is typically treated with surgery. The goal is to reattach the retina and restore vision. Common surgical methods include:
1. Vitrectomy: Removing the vitreous gel and replacing it with a gas or oil to help the retina reattach.
2. Scleral buckling: Placing a flexible band around the eye to push the retina back into place.
3. Pneumatic retinopexy: Injecting a gas bubble into the eye to push the retina back into place.
Both silicone oil and gas are used as tamponades in vitreoretinal surgery to help reattach the retina. The choice between the two depends on the specific case.
Silicone Oil:
-Provides long-term tamponade
– Often used for complex cases or when gas is not suitable
– Can be left in the eye for extended periods
Gas:
– Provides temporary tamponade
– Absorbs on its own over time
– Often used for less complex cases
The extent of vision recovery after vitreoretinal surgery varies depending on:
1. Underlying condition: Severity and duration of the condition.
2. Surgical complexity: Type of surgery and technique used.
3. Individual factors: Overall eye health, age, and healing response.
Possible Outcomes:
– Improved vision: Many patients experience significant improvement.
– Stable vision: Some patients may experience stable vision, but no further improvement.
– Limited recovery: In some cases, vision may not fully recover due to underlying damage.
Realistic Expectations:
It’s essential to discuss individual expectations and potential outcomes with an eye doctor or vitreoretinal surgeon to understand the likelihood of vision recovery.
If you’ve had retinal detachment in one eye, you’re at a higher risk of developing it in the other eye. This is because:
1. Shared risk factors: Conditions like near-sightedness or myopia , diabetes, or family history can increase the risk.
2. Similarities in eye structure: The underlying anatomy of both eyes can be similar.
Risk Factors to Consider:
– Family history: If there’s a history of retinal detachment in your family.
– Near-sightedness: High myopia can increase the risk.
– Diabetes: Diabetic retinopathy can increase the risk.
– Previous eye trauma or surgery: Trauma or surgery to one eye can increase the risk.
Prevention and Monitoring:
– Regular eye exams: Schedule regular check-ups with an eye doctor.
– Report symptoms: If you experience flashes, floaters, or vision changes in the other eye.
The cornea transplants are done at centres recognised for cornea transplantation,ie those centres which have a CTC certificate. So before enrolling your relative for cornea transplantation, it is wise to check that the centre has a CTC certificate . The cornea to be transplanted is sourced by the eye hospital from an Eye Bank that is duly registered and recognised by the State Government.
Thakur Eye Hospital is a duly recognised CTC centre and the working HQ of nationally acclaimed Madhav Netra Bank an Eye bank working towards the cause of eradication of Corneal Blindness
For information about pledging or donating eyes, please contact Thakur Eye Hospital at +91 822 208 8094 or visit the Eye Bank page on this website. The hospital team can guide you regarding the current process and required formalities.
To prevent myopia progression in children, consider the following evidence-based strategies:
a)Outdoor Time
Encourage your child to spend at least 80-120 minutes outdoors daily, as studies suggest this can reduce the risk of myopia onset and progression by 9% after 3 years. Outdoor time is essential, especially during early childhood, to prevent myopia development.
b)Low-Dose Atropine
– Low-dose atropine (0.01%) eye drops have been shown to slow myopia progression with minimal side effects.Studies suggest starting treatment early can be beneficial, especially for children at high risk
c) Specialized Spectacle Lenses
– Diversified segmental defocus optimization (DSDO) spectacle lenses can delay myopia onset and slow progression in children.
– These lenses work by providing a specific peripheral defocus pattern that helps manage eye growth
d)Orthokeratology (OK) Lenses
– OK lenses can slow down myopia progression by reshaping the cornea while your child sleeps, reducing axial elongation. Studies show OK lenses are more effective in younger children and those with high myopia
e) Multifocal Lenses: Multifocal lenses with myopic defocus can slow down myopia progression by 36.4% and reduce axial elongation by 37.9%. These lenses work by providing peripheral myopic defocus, which helps control eye growth.
f) Behavioural Interventions
Monitoring and feedback on eye-use behaviour can help delay myopia onset and progression. Encourage your child to follow good eye care habits, such as taking regular breaks from near work and maintaining good posture
The ideal age for LASIK surgery depends on various factors, including:
1. Stable vision: Your prescription should be stable for at least a year before considering LASIK.
2. Age: Typically, candidates should be at least 18 years old, as vision can change significantly during adolescence.
3. Eye health: Certain eye conditions, such as cataracts, glaucoma, or keratoconus, may affect candidacy.
4. Corneal thickness: The cornea should be thick enough to allow for safe reshaping.
Age Guidelines
5. Minimum age: 18 years old (some surgeons may consider younger patients with stable vision)
6. Optimal age range: 20-40 years old (vision is often more stable during this period)
Broadly there are three treatment options for squint. These are:
1. Glasses or contact lenses: Correcting refractive errors.
2. Vision therapy: Exercises to improve eye alignment and coordination.
3. Surgery: Adjusting the eye muscles to improve alignment.
Suitability for LASIK depends on factors such as a stable spectacle or contact-lens prescription, corneal measurements, overall eye health, medical history and individual expectations. A detailed pre-operative eye examination is required before deciding whether LASIK is appropriate.
An Implantable Collamer Lens (ICL) is a type of phakic intraocular lens placed inside the eye while the natural lens remains in place. LASIK, by contrast, changes the shape of the cornea. The more appropriate option depends on the individual eye and refractive error.
No refractive procedure can guarantee complete freedom from glasses for every patient. The aim is to reduce dependence on spectacles or contact lenses, but results and future visual needs vary between individuals.
The decision is made after assessment of the refractive error, stability of the prescription, corneal and other eye measurements, overall ocular health, medical history, lifestyle and expectations.
Yes. Contact lenses should be prescribed and fitted after an eye examination. The eye-care professional checks vision, eye health and how the selected lens fits before advising wear and care.
Replacement schedules vary by lens type. Follow the schedule advised by your eye-care professional and the instructions for the specific lenses you have been prescribed.
Contact lenses should generally be kept away from water. Remove them before swimming or showering unless your eye-care professional has given specific advice for your situation.
Remove the lenses and seek eye-care advice promptly if you develop significant redness, pain, light sensitivity, discharge, persistent discomfort or blurred vision.
Oculoplasty is the area of ophthalmic care concerned with the eyelids, tear-drainage system, eye socket and surrounding tissues.
An evaluation may be advised for problems such as abnormal eyelid position, persistent watering, eyelid lesions, injury or other conditions involving the tissues around the eye. The exact assessment depends on the individual problem.
No. Treatment depends on the cause and severity of the condition. Some problems may be observed or treated medically, while others may require a procedure or surgery after appropriate evaluation.
Watering can have several causes, including irritation of the eye surface, eyelid problems or difficulty with tear drainage. Examination helps identify the likely cause and guide treatment.
