CATARACT SURGERY COMPLICATIONS
Early complications of intraocular lens (IOL) surgery include corneal edema, wound leak, shallow anterior chamber, hyphaema, retained lens matter, and uveitis. Late complications include posterior capsular opacification, cystoid macular edema, endophthalmitis, and retinal detachment. Post-operative endophthalmitis is a vision-threatening complication that is treated with topical, systemic, and intravitreal antibiotics along with steroids. Posterior capsular opacification occurs in 10-50% of cases due to proliferation of lens epithelial cells.
Complications of.........
Some potential complications from cataract surgery include: corneal abrasion from Schiotz tonometry; retrobulbar hemorrhage from retrobulbar block requiring pressure bandaging; oculocardiac reflex from retrobulbar block treated with atropine; perforated globe risk minimized with gentle injection; subconjunctival hemorrhage requiring no treatment. Posterior dislocation of the lens during retrobulbar block requires postponing surgery and managing as a posterior dislocation.

Extracapsular cataract extraction
Extracapsular cataract extraction (ECCE) is a type of eye surgery where the lens is removed while leaving the elastic capsule partially intact to allow implantation of an intraocular lens. This contrasts with intracapsular cataract extraction where the whole lens and capsule are removed. ECCE can be performed conventionally through a 10-12mm incision or with smaller incisions using phacoemulsification. Potential complications include posterior capsule tear, dropped nucleus, vitreous loss, raised intraocular pressure, and late complications such as cystoid macular edema and glaucoma. Careful surgical technique and postoperative management can help reduce risks.

Glaucoma post cataract surgery .pdf
Glaucoma can occur after cataract surgery due to various mechanisms. Early causes within the first few days include retained viscoelastic material, inflammation, hyphema, pupillary block, and malignant glaucoma. Late causes after 2 weeks can be steroid-induced glaucoma, changes to the trabecular meshwork from aphakia, peripheral anterior synechiae, epithelial ingrowth, retained lens matter, or uveitis-glaucoma-hyphema syndrome from intraocular lens complications. Prevention involves careful removal of viscoelastic and control of inflammation, while treatment depends on the underlying cause and may include medical management, removal of viscoelastic, or surgery.

Late causes after 2 weeks can be steroid-induced glaucoma, changes to the trabecular meshwork from aphakia, peripheral anterior synechiae, epithelial ingrowth, retained lens matter, or uveitis-glaucoma-hyphema syndrome from intraocular lens complications. Managing the underlying cause through medical or surgical treatment is important to control post-operative glaucoma.
Ectropion
This document provides information about ectropion, including:
1. It defines ectropion as eversion of the eyelid where the lid rolls away from the globe.
2. It classifies ectropion into categories such as congenital, involutional, cicatricial, paralytic, and mechanical.
3. It describes the evaluation, causes, clinical features and complications of different types of ectropion, as well as various surgical and non-surgical management approaches.
Malignant glaucoma
Malignant glaucoma is a complication that can occur after glaucoma filtration surgery where the anterior chamber becomes shallow despite a patent iridotomy. It is caused by abnormal accumulation of aqueous humor behind the lens and iris, causing the iris-lens diaphragm to move forward. Theories of its cause include posterior diversion of aqueous flow, anterior displacement of the vitreous, or pressure from an expanded choroid pushing the lens forward. Treatment involves cycloplegics to pull the lens back, reducing aqueous production and IOP, and sometimes laser treatment or vitrectomy surgery to disrupt the abnormal fluid buildup.
Glaucoma associated with ocular trauma and intraocular haemorrhage,inflammatory
Glaucoma can develop due to ocular trauma, inflammation, or intraocular hemorrhage. Trauma-induced glaucoma is caused by angle recession, uveal effusion, or proliferative changes in the trabecular meshwork. Intraocular hemorrhage like hyphema can lead to glaucoma if blood cells obstruct the outflow tract. Inflammatory glaucoma occurs when inflammatory cells or debris block the trabecular meshwork, as seen in conditions like sarcoidosis, juvenile rheumatoid arthritis, and ankylosing spondylitis. Management involves medical treatment, laser trabeculoplasty, or filtering surgeries depending on the underlying cause and severity of glau
A Protocol For Uveitis Patients Undergoing Cataract Surgery
The document discusses guidelines for performing cataract surgery on patients with uveitis. It outlines several challenges including pre-operative and post-operative inflammation control and technical difficulties during surgery. The guidelines recommend thorough pre-operative control of inflammation, careful surgical techniques such as phacoemulsification instead of extracapsular extraction, and strict post-operative anti-inflammatory treatment to minimize complications for these high-risk patients. Special considerations are discussed for different types of uveitis.

- 4. 1. HYPHAEMA Collection of blood in the anterior chamber may occur from conjunctival or scleral vessels Treatment Most hyphaemas absorb spontaneously and does need no treatment. Acetazolamide used ( when associated with raised IOP )
- 5. 2. IRIS PROLAPSE Usually caused by inadequate suturing of the incision after ICCE and conventional ECCE Management The prolapse may be reposited back and wound sutured.
- 6. 3. STRIATE KERATOPATHY Characterized by mild corneal oedema with descemet's folds . This occurs due to endothelial damage during surgery. Management Mild - disappears within a week Moderate to severe - installation of hypertonic saline drops (5% NaCl) along with steroids
