Doctors use a variety of anaesthetics for cataract surgery. You may take a Valium pill to help you relax and feel drowsy during the procedure. Sometimes we may give you medication in an intravenous catheter put in a vein in your arm. We also use anaesthetic eye drops to numb your eye before the surgery begins.
Most cataract surgeries employ the following medications singularly or in some combination: midazolam, fentanyl, ketamine, and propofol. Ten years ago, our surgical center preferred midazolam and fentanyl.
Typically, patients are awake during cataract surgery. This eliminates risks associated with general anesthesia (where you are “put to sleep”) and enables Our Doctors to communicate with you during your procedure. You will be given an oral medication prior to the procedure to help you relax during your surgery.
Along with the anesthetic to the eye, in most cataract surgeries an anesthetist will also give you some mild sedative medication through an IV. This relaxes you but does not put you “out,” although some people do fall asleep during the procedure from the effects of the sedation.
In addition, some patients become claustrophobic under the drape and others may experience a variety of visual sensations that up to 15% find frightening. Various studies have been undertaken looking into factors that cause anxiety and into the emotional aspects of cataract surgery.
During cataract surgery
You'll be awake during surgery, but you won't be able to see what's happening in your eye. Our ophthalmologists at Beverly Hills Institute of Ophthalmology perform cataract surgery using a state-of-the-art femtosecond laser.
The patient sits upright or semi-recumbent, and the surgeon sits or stands, facing the patient. The microscope is rotated forward, and surgery is done via an incision in the lower half of the cornea, using topical intracameral anesthesia.
CATARACT SURGERY: Cataract surgery is usually performed using numbing local anesthetic eye drop medications. Patients are wake or mildly sedated, and no airway tube is used. COLONOSCOPY OR STOMACH ENDOSCOPY: These procedures are performed under intravenous sedation and almost never require an airway tube.
Cataract surgery is not painful. While patients are awake during surgery, there is little or no discomfort involved. A mild sedative may be administered before the surgery, which calms the nerves, and eye drops are used to numb the eye.
Patients for cataract surgery in India routinely undergo preoperative syringing to rule out chronic dacryocystitis. We determined the sensitivity and specificity of the clinical test of regurgitation on pressure over the lacrimal sac (ROPLAS) as a screening test for chronic dacryocystitis and compared it to syringing.
At the beginning of surgery, your ophthalmic surgeon will clean the skin around the eye and place a plastic cover on the eyelid so that partially covers your face and if your surgery is under local anaesthetic you have some oxygen to breathe and space around your mouth to feel comfortable and non-claustrophobic.
Anesthesia paralyzes your muscles. This stops movement in the intestinal tract. Until your intestines "wake up," there is no movement of stool.
Answer: Anesthesia
For most shorter procedures and in the right individual, an LMA or laryngeal mask airway is used which just goes down to the back of the throat. An endotracheal tube will go below the vocal cords. Best to discuss with your anesthesiologist.
If you're having general anesthesia, an anesthesiologist will give you medications that make you lose consciousness. After the surgery is complete, he or she will reverse the medication so that you regain consciousness — but you won't be wide awake right away.
Plan on taking one to three days off of work to be sure you have enough time to rest, but it is normal to resume most normal activities within a couple of days. Simple diversions like reading, watching TV, writing, and walking are okay to resume as soon as you feel up for it after your eye surgery.
Cataract surgery patients often worry about what may happen if they blink during the procedure. Although this is an understandable concern, there is no need to worry. You will be given an oral medication prior to the procedure to help you relax during your surgery.
During surgery, the physician/anesthesiologist will monitor your heart rate, blood pressure, breathing and other vital signs. And you remain unconscious, free of pain. Once the operation is completed, the doctor will reverse the medication and wake you up.
Are you awake during cataract surgery? Yes, patients typically stay awake during cataract surgery — but don't worry. You won't be able to feel or see the surgeon operating on your eye.
Anxiety is particularly important, because it has the potential to affect all aspects of anesthesia such as preoperative visit, induction, perioperative, and recovery periods [2, 3].
“High eye pressure can interfere with the incision before it fully heals,” says Eghrari. “Positions that put your head below your waist, such as bending over, can also increase eye pressure and should be avoided initially after surgery.”
The following drops should be applied to your operated eye only, starting the morning after surgery. Chloramphenicol One drop, four times Antibiotic (store in fridge) a day for 2 weeks, then stop. Dexamethasone One drop, four times Anti- (Maxidex) a day for 4 weeks, inflammatory then stop.
Dry eye-associated symptoms, such as foreign body sensation and fatigue, frequently occur after cataract surgery. Affected patients may experience red or watery eyes along with constant foreign body sensation. Several published studies have documented the aggravation of dry eye symptoms and signs after LASIK and PRK.
Your Recovery
After surgery, your eye may feel scratchy, sticky, or uncomfortable. It may also water more than usual. Most people see better 1 to 3 days after surgery. But it could take 3 to 10 weeks to get the full benefits of surgery and to see as clearly as possible.
