Phacoemulsification cataract surgery, which is a safe procedure with a low incidence of complications, is quickly becoming the primary strategy for treating cataracts today. The great majority of patients notice a significant improvement in their vision after a short, painless procedure that is performed on an outpatient basis in the majority of cases. However, although complications after cataract surgery are exceedingly uncommon, they may occur and have a severe influence on the patient’s ability to see well.
Due to the fact that many of these concerns are obvious the day after the treatment, it is recommended that patients be checked the next morning after cataract eye surgery. In this way, any issues that are detected may be treated in a timely manner, allowing for the most suitable healing and recovery to occur.
Complications that are just temporary: These often signal that you should seek medical assistance right away.
Ocular edema (blurred vision) may develop as a consequence of the surgical trauma, particularly as a result of the ultrasonic energy and the fluid that is injected into the anterior chamber. Eyesight will be clouded as the endothelial cells struggle to remove the water from the corneal stroma, and the vision will remain obscured until the water has been eliminated. Fortunately, since high-quality viscoelastic materials are used in cataract surgery, corneal edema is less common. However, prolonged cataract surgery on a thick nucleus might result in localized or even extensive swelling of the cornea. Treatment with steroids to reduce inflammation, as well as the administration of a hypertonic saline solution, may help to hasten the return of vision.

High intraocular pressure (IOP) The intraocular pressure (IOP) should be within physiologic limits for the vast majority of patients. Depending on whether an incision has been made and the amount of leftover viscoelastic, the amount of residual viscoelastic may be more or lower. High intraocular pressure (IOP) may be treated medically using topical and oral drugs, but the patient should be monitored on a continual basis during the treatment process.
When the viscoelastic has been evacuated from the anterior chamber, the pressure in the chamber returns to its usual state. Aqueous release may be achieved by tapping the anterior chamber, although this procedure is not generally recommended since it is often just a short-term solution and exposes the eye to an increased risk of infection.
Due to the fact that surgical operations usually create some degree of inflammation, it is normal to notice some anterior chamber cells and a flare the day following the cataract surgery. You should seek medical attention if you have an abnormally strong anterior chamber response to fibrin or a hypopyon. This is not normal and may suggest inflammation caused by toxic anterior shock syndrome or endophthalmitis.
Despite the fact that both need monthly steroid medication to keep the inflammation under control, the latter requires a diagnostic tap, an antibiotic injection, and fast intervention to prevent eyesight and the eye from being irreparably damaged or lost altogether. Endophthalmitis may manifest itself as early as the first postoperative day, despite the fact that the usual manifestation of the disease occurs many days following cataract surgery.
The presence of anatomic problems indicates the need for surgical intervention.
Phacoemulsification may result in the retention of small cataract pieces in the anterior chamber, which is a potentially dangerous situation. This happens when the cataract is split into numerous pieces during the cataract surgery, and a little portion of the cataract may linger in the anterior chamber after the procedure. They have the potential to cause substantial irritation and localized damage to the cornea if they are swallowed by the patient. Learn more recommendations from experts for cataract surgery.
The treatment of a tiny, wispy cortical piece may be accomplished medically with steroids and focused application of the YAG laser to break it up into smaller fragments and increase the surface area to volume ratio, but larger pieces would need surgical intervention. In cases of cataract surgery when there has been a posterior capsule rupture and there are residual lens pieces in the vitreous, a pars plana lensectomy and vitrectomy may be recommended in addition to the cataract surgery. Whenever possible, a referral to an experienced vitreoretinal specialist is suggested in the case of cataract surgery.
Subluxation of the IOL (internal ophthalmic ligament):
A subluxation may occur if the IOL implant is not correctly secured, allowing it to fall out of its original position and become dislocated. The presence of this condition is more common in instances where the lens was implanted into the ciliary sulcus because of a defect in the posterior capsule of the eyeball, as opposed to other situations. However, although it is possible to notice little episodes of IOL subluxation, any substantial movement away from the visual axis should be corrected surgically. Certain scenarios necessitate the use of this form of suture attachment, which may aid in the long-term stability and centration of an intraocular lens (IOL).
An incision with a leak: If the IOP is low, it is probable that there is leaking from the incision. The use of a fluorescein dye leakage test may aid in the identification of the source of the leak and the determination of the extent of the fluid leakage. Significant leakage from an incision indicates that a suture will almost probably be required to close the wound and prevent further hypotony as well as the risk of infection from forming. As a result, the presence of iris tissue trapped within an incision is a strong sign that there is a problem with the incision when there is a leaking incision.
Complications that persist over an extended period of time
Even though many of the potential complications associated with cataract surgery may be diagnosed on the first postoperative day, some may take a little longer to reveal themselves. In the aftermath of cataract surgery, retinal issues such as cystoid macular edema and retinal fractures are prevalent, and they might reveal themselves many days or weeks after the treatment. It is only after the capsular bag has been closed and the IOL has been implanted in its final position that the relative refractive errors can be properly evaluated, and this process takes time. Because it happens so often and reveals itself weeks or months after cataract surgery, we may not even consider posterior capsule opacification to be a side effect of the treatment.
Despite the fact that modern cataract surgery is a brilliant operation, it nevertheless need the assistance of an ophthalmologist during the procedure and for a period of time thereafter. At the end of the day, both the surgical approach used and the healing process that happens during the postoperative period influence the ultimate visual outcome for the patient.
