What are the contraindications of cataract surgery?

Contraindications to surgery include cataracts without visual impairment or medical/ophthalmic conditions that do not allow for safe surgical outcomes.

What are the postoperative complications of cataract surgery?

Complications

  • Posterior Capsule Rupture/Vitreous loss.
  • Cystoid Macular Edema.
  • Endophthalmitis.
  • Vitreous/Suprachoroidal Hemorrhage.
  • Retinal Tears/Detachment.
  • Lens Dislocation.

What are complications of phacoemulsification?

The most common postoperative complication was posterior capsule opacification (21.5%) and elevated intraocular pressure (9.7%), macular edema (8.1%), fibrinous reaction (6.9%), vitreous hemorrhage (3.7%), posterior synechiae (3.7%), and recurrent retinal detachment (3.2%).

Why does PCO occur after cataract surgery?

PCO occurs because cells remaining after cataract surgery grow over the back (posterior) of the capsule causing it to thicken and become slightly opaque (cloudy). This means that light is less able to travel through to the retina at the back of your eye.

What is Pseudoexfoliation syndrome?

Pseudoexfoliation syndrome (PXF or PEX) is an age-related systemic syndrome that targets mainly ocular tissues through the gradual deposition of fibrillary white flaky material from the lens, mainly on the lens capsule, ciliary body, zonules, corneal endothelium, iris and pupillary margin.

What is ghosting after cataract surgery?

Ghosting vision or double vision, also more properly known as diplopia, is a condition that occurs when your eyes that normally work together start to see two slightly different images. Double vision occurs when these two different images cause you to see them transposed next to each other.

What is Dysphotopsia?

dysphotopsia—positive and negative—that can occur after cataract surgery. “Dysphotopsia just means an unwanted image that patients see after cataract surgery.

What causes corneal edema after cataract surgery?

The two most common conditions that can cause corneal edema after cataract surgery are Fuchs’ dystrophy and retained lens fragments after surgery. Fuchs’ dystrophy can be treated with a phacoemulsification procedure alone or a Descemet’s stripping endothelial keratoplasty (DSEK) triple procedure, Kim said.

What are the risks of nasogastric suction?

Nasogastric suction risks may include: 1 Breathing in contents from the stomach (this is called aspiration) 2 Hole (perforation) in the esophagus 3 Placing the tube into the airway (windpipe) instead of the esophagus 4 Minor bleeding

What are the possible complications of nasogastric (NG) tubes?

While properly inserted nasogastric (NG) tubes are useful, if precautions are ignored, they can lead to several complications. These include: The tube may enter the lungs Because of the proximity of the larynx to the oesophagus, the nasogastric tube may enter the larynx and trachea (Lo et al, 2008).

What are the most common cataract surgery side effects?

Other potential cataract surgery side effects range from minor eye inflammation to serious vision loss. Minor side effects can include: These minor complications usually clear up with medications and more healing time. The risk of severe vision loss is very low.

What happens if a nasogastric tube is mispositioned?

Nasogastric tube insertion is mostly done blindly by the bedside with about 0.5% to 16% mispositioning in the pleura, trachea or bronchial trees. This can cause the infusion of enteral feeds in the tracheobronchial tree causing a pulmonary abscess or pneumothorax 21).
