People who have a multifocal intraocular lens after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [2] People receiving multifocal lenses may experience more visual problems, such as glare or haloes (rings around lights), than with monofocal lenses. [2] People ...
People who have a multifocal IOL after their cataract is removed may be less likely to need additional glasses compared with people who have standard monofocal lenses. [6] However, people receiving multifocal lenses may experience more visual problems than with monofocal lenses. [6]
IOLs can be used to correct other vision problems, such as toric lenses for correcting astigmatism. [39] IOLs can be classified as monofocal, toric, and multifocal lenses. [40] Ocular anaesthesia has improved since Alfred Einhorn synthesised procaine in 1905, which was used in retrobulbar anaesthesia.
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing tunnel wound through the sclera. A well-constructed scleral tunnel is held closed by internal pressure, is watertight , and does not require suturing.
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema; it is also associated with increased risk of endophthalmitis and retinal detachment.
Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
