Ahmed Glaucoma Valve Implant
Steps Involved in IVF:
Procedure Description
The Ahmed Glaucoma Valve Implant (AGV) is a specialized surgical intervention designed for glaucoma patients who do not respond adequately to conventional treatments like medication or laser therapies. Glaucoma, characterized by elevated intraocular pressure (IOP), can lead to progressive damage to the optic nerve, resulting in vision loss. This implant is a drainage device that helps lower the eye pressure by providing an alternative pathway for fluid (aqueous humor) to exit the eye.
The AGV consists of a small, flexible silicone tube attached to a broader plate, which is implanted under the conjunctiva (the thin membrane covering the eye). The device regulates the flow of the aqueous humor from the anterior chamber of the eye (front part) to a small space formed beneath the plate called the bleb. The valve in the implant ensures that fluid drains at a controlled rate, preventing both high and abnormally low eye pressures, which can be harmful.
The primary goal of the AGV implant is to reduce IOP and protect the optic nerve from further damage. It is commonly indicated for cases of refractory glaucoma—glaucoma that is difficult to manage due to resistance to standard treatments or the presence of additional complicating factors such as neovascular glaucoma, uveitic glaucoma, or congenital glaucoma.
Procedure Duration
The Ahmed Glaucoma Valve Implant surgery is typically an outpatient procedure, meaning the patient can go home the same day. The entire process usually lasts between 45 minutes to an hour. However, the duration can vary based on factors such as the type of glaucoma, the complexity of the patient's anatomy, and any pre-existing eye conditions.
Pre-Surgical Preparation: Before the procedure, a thorough examination is conducted, including measurement of IOP, visual field testing, and eye imaging to determine the extent of optic nerve damage. Local anesthesia is used to numb the eye, and patients are often given sedatives to ensure they remain comfortable and relaxed during the surgery.
Surgical Phases: The procedure begins with creating a small incision in the conjunctiva to access the implantation site. The plate of the AGV is placed in the selected area, typically on the surface of the sclera (the white part of the eye). The tube is then carefully inserted into the anterior chamber of the eye to facilitate controlled fluid drainage. Once in place, the implant is secured, and the incision is closed with sutures. A protective eye shield may be applied to prevent injury post-surgery.
Post-Surgical Recovery: After surgery, patients are closely monitored to ensure proper healing and stabilization of IOP. The full recovery process generally spans 4-6 weeks, during which regular follow-up visits are necessary to assess the implant's function and address any complications. Patients are prescribed eye drops to prevent infection and inflammation and may need to avoid strenuous activities during this time to promote optimal healing.

Risks & Considerations
- Risk of Infection: As with any surgery, there is a potential risk of infection. Postoperative care, including the use of antibiotic eye drops, is crucial to minimize this risk.
- Implant Malfunction: Although rare, there is a possibility that the valve may not function as intended, requiring additional interventions or adjustments.
- Diplopia or Double Vision: Some patients may experience temporary double vision after surgery, which typically resolves over time but may require corrective treatment in rare cases.
- Hypotony or Overdrainage: While the valve is designed to prevent overdrainage, there is a small risk of the implant draining too much fluid, resulting in low IOP that may necessitate further management.
- Bleeding or Hyphema: Some patients might experience bleeding within the eye (hyphema) post-surgery, which usually resolves on its own but requires close monitoring.
How to Choose the Right Doctor and Hospital
When seeking treatment for glaucoma with an Ahmed Glaucoma Valve Implant, it is crucial to research thoroughly to find a reputable doctor and hospital. Here are some practical tips to guide your choice:
- Check Credentials and Experience: Opt for a board-certified ophthalmologist who specializes in glaucoma surgery. The doctor should have extensive experience performing AGV implant procedures and be well-versed in managing potential complications.
- Consider the Facility’s Accreditation and Technology: Choose a hospital or clinic that is internationally accredited and equipped with the latest eye care technologies. High-quality facilities will provide better care, more precise procedures, and a more comfortable recovery experience.

Frequently Asked Questions
What actually happens during hyperstimulation of the ovaries?
The patient will take injectable FSH (follicle stimulating hormone) for eight to eleven days, depending on how long the follicles take to mature. This hormone is produced naturally in a woman’s body causing one egg to develop per cycle. Taking the injectable FSH causes several follicles to develop at once, at approximately the same rate. The development is monitored with vaginal ultrasounds and following the patient’s levels of estradiol and progesterone. FSH brand names include Repronex, Follistim, Menopur, Gonal-F and Bravelle. The patient injects herself daily.
What happens during egg retrieval?
When the follicles have developed enough to be harvested, the patient attends an appointment where she is anesthetized and prepared for the procedure. Next, the doctor uses an ultrasound probe to guide a needle through the vaginal wall and into the follicle of the ovary. The thin needle draws the follicle fluid, which is then examined by an embryologist to find the eggs. The whole process takes about 20 minutes.
What happens to the eggs?
In the next step, the harvested eggs are then fertilized. If the sperm from the potential father, or in some cases, anonymous donor, has normal functionality, the eggs and sperm are placed together in a dish with a nutrient fluid, then incubated overnight to fertilize normally. If the sperm functionality is suboptimal, an embryologist uses Intracytoplasmic Sperm Injection to inject a single sperm into a single egg with an extremely precise glass needle. Once fertilization is complete, the embryos are assessed and prepared to be transferred to the patient’s uterus.
How are the embryos transferred back to the uterus?
The doctor and the patient will discuss the number of embryos to be transferred. The number of successfully fertilized eggs usually determines the number of eggs to be placed in the uterus. Embryos are transferred to the uterus with transabdominal ultrasound guidance. This process does not require anesthesia, but it can cause minor cervical or uterine discomfort. Following transfer, the patient is advised to take at least one days bed rest and two or three additional days of rest, then 10 to 12 days later, two pregnancy tests are scheduled to confirm success. Once two positive tests are completed, an obstetrical ultrasound is ordered to show the sac, fetal pole, yolk sac and fetal heart rate.
Embryoscope©
Built into this technology there is a microscope with a powerful camera that allows the uninterrupted monitoring of the embryo during its first hours of life. In this way, we can keep a close eye on the embryo, from the moment when the oocyte is inseminated and begins to divide into smaller and smaller cells, until it can be transferred to the uterus.
