Cataract surgery is probably the most common surgery type performed worldwide. While the vast majority of surgeries lead to great outcomes, the large volume of operations raises the likelihood that any surgeon may experience an unpleasant surprise from time to time. With this in mind, 3 expert surgeons provide guidance regarding how to manage several of the issues that a cataract surgeon may encounter – and, where possible, how to stay away from them altogether.

Proactive Planning

Obviously, the most effective strategy to handle intraoperative difficulties during a cataract surgery sydney is usually to take 2 steps: First, decrease the possibility of an occurrence; as well as next, be ready in the event of a setback. In that vein, Audrey R. Refractive surgeon, cataract, a cornea, MD, and Talley Rostov at Northwest Eye Surgeons in Seattle, tends to make the following tips.

Anticipate difficulties almost as possible. 

“There are many strategies to anticipate such difficulties in a cataract surgery sydney in advance,” Dr. Rostov observes. “First and foremost, in case you anticipate a far more difficult case than normal, one you don’t face often, like a sutured IOL, evaluate the cataract surgery procedure with the team of yours in advance.

“Second, understand when to use special equipment to avoid a problem during a cataract surgery,” she explains. “For example, the capsule is much more flexible in an extremely young kid, making capsulorhexis more difficult. If you’ve a femtosecond laser available to do the capsulorhexis, this might be a suitable application.

“Third, have specialized instruments on hand,” she explains. “If the affected person is in his 90s or perhaps very young, has a rock hard nucleus or perhaps traumatic cataract, or perhaps has a suspected or perhaps evident zonular dehiscence or perhaps dialysis, you need to be equipped with all of the instruments necessary to deal with cataract surgery conditions.”

For example, if a patient has an enhanced, thick, cream, or perhaps brown cataract, I want to have Malyugin rings, intraoperative epinephrine, Trypan blue, iris hooks, and a vitrectomy equipment ready in the home in case of an issue. Clearly, they’re not needed in every circumstance, but getting the equipment found eliminates the necessity for your Or perhaps personnel to go searching for it.

“Fourth, usually have a backup lens on hand in case the bag or even the zonules fail,” she advises. “While this’s not an ordinary occurrence during a cataract surgery sydney, you have to be ready for it. The STAAR AQ2010 is likely the best sulcus lens, as the focal length of its is 13.5 mm rather compared to thirteen mm. Maintain a three-piece IOL as a backup; these may be utilized in the sulcus providing you’re mindful of the limits of theirs. Hopefully, at this point, every doctor appreciates that a single piece acrylic IOL should not be placed in the sulcus.”

When confronted with adversity, employ other tactics. 

“Complications might occur whether regular practice is followed in an atypical setting,” Dr. Rostov cautions. “For instance, if the nucleus is adherent and thick very to the capsule, phaco chop may result in difficulties. In case that is such, I sculpt almost as possible and make a massive bowl which will ultimately fall on itself. I may then viscodissect it from the posterior capsule using viscoelastic. This significantly decreases the risk of complications.”

Prevent your vision from being blocked. 

“At times, while the assistant is squirting BSS on the cornea, it might temporarily impair your visibility,” Dr. Rostov says. “During that brief obliteration of the vision of yours, you risk phacoing the capsule, puncturing the posterior capsule, or perhaps understanding the anterior capsule. The strategy is usually to make certain that the assistant of yours only irrigates briefly and just if you specifically request it. Then you will understand when you should anticipate it and the perspective of yours will not be clouded when you least expect it, like during an important move.”

Be on the search for warning signals. 

“Whenever something out of the norm occurs, pause and take a minute,” she advises. “Take a look around and be acutely aware of the surroundings of yours. This’s particularly critical in non-routine instances or people who have the potential to be difficult.”

Complications of the Cornea 

With clean corneal incisions becoming more widespread in contemporary cataract surgery, various corneal problems are possible.

Abrasions to the cornea. 

“Corneal abrasions are able to occur during the wound formation process or perhaps due to a tool slipping over the eye, like while inserting the speculum,” explains Robert Weinstock, MD, director of cataract and refractive surgery at the Eye Institute of West Florida in Largo, Fla. “Almost some tool used in cataract surgery has the potential to cause an epithelium abrasion, and in a few cases, an epithelial abrasion is able to block the surgeon ‘s eyesight during the process.

“The surgeon has numerous cataract surgery solutions to him, with regards to the size and location of the abrasion,” he explains. “One possibility is usually to apply a cohesive viscoelastic to the cornea to increase surgical visibility and conceal the abrasion. Another strategy is usually to debride the central epithelium; however this’s commonly used as a last option and just if the vision into the eye is significantly restricted because of a damaged or foggy epithelium.

“At the conclusion of the case, I propose placing a soft contact lens on the eye to alleviate severe discomfort and promote healing,” he says.

Burns to the wound. 

While wound burn is much less common these days because of better phaco power modulation and laser cataract softening, it’s nonetheless possible if an especially thick nuclear fragment becomes lodged in the phaco needle handpiece or perhaps tubing and prevents aspiration passage from the eye,” Dr. Weinstock explains. “If you are at foot position 3 and no fluid is bleeding out from the eye via the needle, the eye will heat up sufficiently to induce thermal injury to the cornea. Once this occurs, the consequences could be quite severe.

“Something must be obstructing the phaco needle, handpiece, and tubing in order for this series of events to occur,” he says. “A clog can occasionally be induced by a thick dispersive viscoelastic or even a nucleus particle. in case you step on the phaco pedal when a clog stops fluid from cooling the phaco needle from flowing, you risk developing a wound burn, even when you are using a fresh phaco machine with pulse modes. 

Usually, you will find a number of indications that anything is wrong; for instance, you may see plumes of white smoke in the anterior chamber and nothing seems to be draining out of the eye via the phaco needle. Also, you will most likely notice the cornea begins to appear coagulated and yellowish, usually on the front lip of the incision. When you see this, it’s generally’ game over.’

“If you detect a blockage or perhaps obstruction, you have to immediately cease operations,” he advises. “Remove the phaco needle out of the eye and flush the tip, handpiece, and tubing with sterile water. The bulk of the time, I learn the cause is a thick nucleus lodged in the tube.
