PEDIATRIC CATARACT SURGERY
Cataract in children is uncommon but a sight-threatening condition. It requires the effort on the part of the parents, pediatrician, pediatric ophthalmologist, and anesthetist for the diagnosis of the condition at the earliest. The child needs to undergo cataract surgery as early as possible.
The surgery is technically more difficult than routine cataract surgery as the eye of the child is very different structurally from the eye of an adult, the best cataract surgeon in Kolkata. The child’s eye needs to undergo vitrectomy to prevent opacification of the visual axis post-surgery though many a time they may need membranectomy later in life.
The child needs to undergo amblyopia therapy for prolonged periods after cataract surgery as the vision takes time to improve. There is a lifelong chance of glaucoma refractive changes need for glasses and a retina check. These kids need 6 monthly follow-ups often for several years later.

ADULT CATARACT SURGERY
Patients may sometimes find this more after cataract surgery as the self-appreciation of these floaters increase after cataract surgery as more light enters the eye. Some patients may feel side vision obstruction after cataract surgery. This is called negative dysphotopsae and happens due to light and lens edge interaction. This usually settles down in one-year time. The need to wear a glass after a cataract depends on the choices of IOL done preoperatively. Each eye is unique and in spite of best efforts, patients may need to wear glasses after cataract surgery.
Postoperative recovery usually takes 2 weeks but, in some cases, may extend up to 6-8 weeks which would mean prolonged medication use. One of the reasons for prolonged recovery is the collection of fluid in the retina a condition called CYSTOID MACULAR OEDEMA. This condition needs prolonged topical medication.
Postoperative dryness after any eye surgery is common and can result in symptoms like foreign body sensation, irritation, and mild haziness in vision, The best cataract surgeon in Kolkata. This is usually treated by lubricant eye drops over a period of 3-4 months.
Very rarely patients may develop a condition of posterior vitreous detachment (PVD) where patients may experience visual obstruction and various figures along with flashes of light. This condition is a natural aging process that will settle down with time but needs follow-up with retinal examination.
A cataract is a normal aging process of the clear lens which becomes opaque and the patient has a gradual decrease in vision. Patients may have glare-like symptoms, rainbow around lights, and severe loss of vision depending upon the degree of cataract of the patient.
Mature cataracts need to be removed as soon as possible as they can lead to a rise in pressure in the eye and ensuing complications. There are different types of cataracts depending upon the density of the nucleus and zone of opacity. Surgery is the only way to remove the opaque lens and replace it with an artificial clear lens.
Cataract surgery will improve the quality of vision but in rare circumstances, the patient may not find improvement in vision after cataract surgery if the retina or optic nerve of the patient is not working properly. Dense cataracts may prevent preoperative assessment of these conditions, best cataract surgeon in Kolkata. The occurrence of black spots in front of the eyes is a natural phenomenon and can happen at any age.
PEDIATRIC GLAUCOMA SURGERY
How does the trabeculectomy work?
A trabeculectomy creates a new passageway for the fluid that the eye produces to leave the eye more easily and be reabsorbed by the tissues surrounding the eye. Sometimes healing and scar tissue can reduce flow through the new drainage channel. Medications applied at the time of the operation or used in the office shortly after the surgery help to prevent scar tissue from forming, best cataract surgeon in Kolkata.
There are also special devices that can be used along with a trabeculectomy surgery to try to maintain the passageway and regulate the rate of fluid escape. You will be given detailed instructions after your surgery that are specific to your eye’s needs. In general, the following guidelines apply:
The plastic shield should be worn while sleeping for 2 or more weeks after surgery to protect the eye. While outside during the day, sunglasses should be worn to protect the eye from the sun and wind. For the first few weeks, avoid strenuous activities (running, lifting more than 10 pounds), bending, rubbing the eye, wearing eye makeup, and swimming. There are no restrictions on reading, watching TV, using your phone, tablet device, computer, etc but you may tire more easily during these activities.
What are the possible side effects of trabeculectomy surgery?
Possible complications may include, infection, bleeding in the front or back part of the eye, the buildup of fluid between the choroid (inner layer of blood vessels) and the sclera (white outer layer of the eyeball), very low eye pressure, wound leak, best cataract surgeon in Kolkata, need for additional surgical intervention, and other eye surgery complications. In some patients, the eye pressure may increase and an additional surgical procedure in the eye to release scar tissue (needling) at the site of the surgery may be required. However, for many patients, the risk of surgery is lower than the risk of losing vision from glaucoma.
What happens if trabeculectomy does not work?
In case of early failure, breaking the scar at the site of surgery and injection of the anti-scar medication may restore the flow. Starting or adding glaucoma medications may keep your eye pressure controlled.
If trabeculectomy fails and eye pressure is elevated despite using glaucoma medications, the surgical revision of the surgery site to remove the formed scar tissue, tube shunt surgery, best cataract surgeon in Kolkata, and a specific type of laser (cyclophotocoagulation) can be employed to lower the eye pressure.
Will Trabeculectomy cure my glaucoma?
The simple answer is “no”. Glaucoma is a chronic disease that requires constant monitoring and treatment. The trabeculectomy procedure will help to lower your eye pressure. However, it will not reverse any loss of vision that has already occurred.
STRABISMUS SURGERY
Patient information about Strabismus Surgery
Eye muscle surgery is surgery to correct strabismus (eye misalignment) or nystagmus (eye wiggling). The surgery involves moving one or more of the eye muscles to adjust the position of the eye or eyes. Eye muscle surgery may be done as an outpatient procedure on the Same Day.
Risks Associated with Strabismus Surgery
The most common risk of strabismus surgery is a partial or complete failure to correct the condition and/or its effects, including associated symptoms such as double vision. In general, the more complicated the strabismus and its associated conditions, the more difficult it is to completely control the deviation and its effects.
Because the visual system is complex, involving much of the brain, repositioning the extraocular muscles cannot be expected to resolve all problems associated with strabismus. In particular, the potential for binocular teaming of the eyes is known to have a significant effect; that is, the best cataract surgeon in Kolkata, if binocular vision can be achieved or recaptured, the likelihood of additional surgery diminishes.
The net effect is that additional surgery is required in a significant number of cases; the likelihood of more than one surgery, depending on a number of factors, can range from as low as 10% to 50% or more, with an average of between 20 and 25 percent. Most other complications, including anesthetic problems, infection, and potential loss of vision are rare.
Benefits of Strabismus (Eye Muscle) Surgery :
The benefits of surgery are aligned with the goals of surgery and may vary from person to person. Alignment of the eyes may make amblyopia therapy less intense.
Proper alignment may eliminate a range of symptoms such as double vision, eye strain, or fatigue, and restore the normal relationships between the eyes themselves and other facial structures, best cataract surgeon in Kolkata. Only the patient and his family, with the advice of their doctor, can determine if these benefits warrant undergoing strabismus surgery.
Pre-operative instructions :
Eye muscle surgery requires general anesthesia to make your child sleep during the procedure. With general anesthesia, there are important rules for eating and drinking that must be followed in the hours before the surgery, by the best cataract surgeon in Kolkata.
The surgery can range from 45 minutes to 2 hours depending on the type of eye muscle surgery your child needs, The best doctor for cataract surgery is in Kolkata. Recovery from anesthesia may take several hours. Milflox eye drop is to be instilled in the eyes for surgery 4 times 3 days before surgery.

PHACOEMULSIFICATION
Phacoemulsification is a modern and minimally invasive cataract surgery procedure used to restore clear vision in patients with cataracts. During the procedure, the cloudy natural lens of the eye is gently broken into tiny fragments using advanced ultrasound technology and then removed through a small incision. The removed lens is replaced with a clear artificial intraocular lens (IOL), which helps restore the eye’s focusing ability and improve vision. The procedure is typically performed under local anaesthesia, usually does not require stitches, and offers a relatively quick recovery. Your ophthalmologist will assess your eyes and recommend the most appropriate lens and surgical approach based on your individual needs.
