PPV with ILM peeling in post traumatic macular hole

PPV with ILM peeling in post traumatic macular hole

PPV with ILM peeling in post traumatic macular hole Indications for consideration of the surgical management of macular holes are based on the presence of a full-thickness defect. Once this defect has developed, the potential for spontaneous resolution is low. Thus, surgical management is recommended with documentation of a stage 2 or higher, full-thickness macular hole. Stage 1 holes and ... Read More »

Muller’s muscle conjunctival resection (MMCR) For Ptosis

Muller’s muscle conjunctival resection (MMCR) For Ptosis

Muller’s muscle conjunctival resection (MMCR) For Ptosis Müller’s muscle (MM) is a sympathetically innervated upper eyelid muscle that, together with the levator palpebral superioris, elevates the eyelid. The MM resembles smooth muscle, and originates from the levator aponeurosis about 15 mm above the superior tarsus. The MM is adherent to the conjunctiva but easily separable from the levator aponeurosis, and ... Read More »

Modified Blaskovics Operation For Ptosis Repair

Modified Blaskovics Operation For Ptosis Repair

Modified Blaskovics Operation For Ptosis Repair(Transconjunctival Blepharoptosis Surgery) Posterior approach blepharoptosis surgery, via the transconjunctival route, was probably the first method of surgery employed to shorten the levator muscle . In 1923 Blaskovics  first described his technique of extensive dissection of the levator muscle from its surrounding structures prior to its resection. Two sets of sutures were used, the first ...

Eversbusch operation for Ptosis

Eversbusch operation for Ptosis

Eversbusch operation for Ptosis an operation for ptosis of the upper eyelid, consisting of resection of the levator muscle through a skin incision. The Eversbusch procedure consisted of a shortening of the levator by taking a tuck in it, the approach being through the skin of the upper lid. While this operation has proved effective in cases of ptosis of slight ... Read More »

Fixation of Subluxated Intraocular Lens

Fixation of Subluxated Intraocular Lens

Fixation of Subluxated Intraocular Lens Cataract surgery is the most common operation performed by ophthalmologists. Although it has a very high success rate, certain complications may occur. Intraocular lens (IOL) malpositions range from simple IOL decentration to luxation into the posterior segment. Subluxated IOLs involve such extreme decentration that the IOL optic covers only a small fraction of the pupillary ... Read More »

Weis procedure for Entropion Treatment

The Weis procedure for Entropion Treatment

Weis procedure for Entropion Treatment Weis (transverse tarsotomy) procedure for the correction of entropion. This procedure everts the lid margin and produces an anatomic barrier that prevents preseptal orbicularis muscle override and secondary tarsal rotation . It has been advocated for involutional entropion but is best suited for patients with varying degrees of cicatricial entropion. The Weis procedure has been ... Read More »

ECCE for Subluxated Hypermature Cataract

ECCE for Subluxated Hypermature Cataract

ECCE for Subluxated Hypermature Cataract A Morgagnian cataract arises when a cortical cataract becomes hypermature. A cortical cataract is an opacity of the lens cortex or periphery of the lens. An early cortical cataract is often clinically diagnosed by spoke-like or wedge-shaped opacities of the lens, most commonly in the inferior quadrants. As the cataract matures, the lens fibers degenerate, ... Read More »

Phacoemulsification of white cataract

Phacoemulsification of white cataract

Phacoemulsification of white cataract Phacoemulsification (Phaco) is the most common technique used by developed countries. It involves the use of a machine with an ultrasonic handpiece equipped with a titanium or steel tip. The tip vibrates at ultrasonic frequency (40,000 Hz) and the lens material is emulsified. A second fine instrument (sometimes called a “cracker” or “chopper”) may be used from ... Read More »
