The differentiation between a dense white cataract and a soft white cataract is important in devising a surgical plan for phacoemulsification. (cataractcoach.com)
The most common procedure for modern cataract surgery is phacoemulsification 1 . (springer.com)
The making of a continuous circular tear in the anterior capsule during cataract surgery in order to allow expression or phacoemulsification of the nucleus of the lens. (lookformedical.com)
Cataract patients are recommended to undergo phacoemulsification, especially those who need to maintain good visual acuity to drive, fly, or operate machinery and equipment. (scopeheal.com)
Patients at increased risk of developing cataracts may also consider the phacoemulsification procedure. (scopeheal.com)
Phacoemulsification is an outpatient microincision cataract surgery procedure that does not require stitches. (scopeheal.com)
Once the posterior lens cortex and capsule have been hydrodissected, the surgeon can rotate the nucleus within the capsular bag to facilitate removal by phacoemulsification. (scopeheal.com)
Reproducible, precise methods generally produce predictable, excellent outcomes when combining laser surgery with phacoemulsification for cataract removal procedures. (crstoday.com)
It is very rarely done now a days only indicated for patients with very hard cataracts or other situations in which phacoemulsification is considered to have potential problems. (prashantsrivastava.com)
As phacoemulsification became the standard, studies began to demonstrate more sustained IOP lowering following cataract surgery. (keogt.com)
Phacoemulsification (particularly clear corneal phacoemulsification) seems to lower IOP more than manual extracapsular cataract extraction. (keogt.com)
With improved microsurgical techniques, especially with the introduction of extracapsular cataract extraction and phacoemulsification, the incidence of phacoanaphylaxis has decreased dramatically and rarely occurs in its originally described form. (medscape.com)
However, chronic postoperative uveitis following phacoemulsification with retained lens material is still a well-known complication of cataract surgery and is the result of the same pathophysiology as the classically described entity of phacoanaphylaxis. (medscape.com)
While lens fragments may be retained in the anterior or posterior chamber during seemingly uncomplicated cataract surgery, they also may be dislocated posteriorly into the vitreous cavity during phacoemulsification of the nucleus, usually after zonular dehiscence or posterior capsule rupture. (medscape.com)
Two primary surgical techniques are used today with phacoemulsification being the predominant choice. (healthnews.com)

Phacoemulsification is the most commonly recommended surgical method for cataract surgery today. (healthnews.com)
Phacoemulsification constitutes over 90% of cataract surgeries worldwide today and is considered the standard of care. (healthnews.com)
Phacoemulsification is performed with a machine with an ultrasonic handpiece equipped with either a surgical steel or titanium tip which vibrates at 40 kHz or in the ultrasonic frequency range. (healthnews.com)
ECCE is preferred for patients who have very hard cataracts or in other clinical situations when phacoemulsification may not be possible. (healthnews.com)

Refractive errors can be surgically corrected either by reshaping the cornea through laser vision correction or implanting a phakic intraocular lens such as the Visian implantable collamer lens (ICL, Staar Surgical, Monrovia, CA, USA). (biomedcentral.com)
Apart from accuracy in calculating the refractive correction, selection of the appropriate size of the ICL is crucial in achieving a desirable outcome since most postoperative complications associated with this surgery are related to suboptimal lens sizing. (biomedcentral.com)
While cataract surgery has advanced tremendously in the last several years, most of the advances have had to do with the transformation of cataract surgery from a medical procedure to a refractive procedure. (prashantsrivastava.com)

A distinct mechanism is seen following extracapsular cataract extraction. (medscape.com)
Extracapsular cataract extraction (ECCE) involves the removal of almost the entire natural lens while the elastic lens capsule (posterior capsule) is left intact to allow implantation of an intraocular lens. (prashantsrivastava.com)
This surgical technique is also called manual extracapsular cataract extraction. (healthnews.com)
Posterior capsule opacification (PCO) is a common postoperative complication of extracapsular cataract surgery, which is caused by the proliferation and migration of lens epithelial cells and can affect long-term visual outcomes significantly. (bvsalud.org)

Cataract, an opacification of the natural crystalline lens, is a significant cause of reversible blindness worldwide. (springer.com)
A cataract is the progressive opacification of the crystalline lens, an extremely transparent lentil-shaped structure in the eye, which acts as a real lens. (alfaintes.it)
Among the most frequent late complications of cataract extraction surgery is opacification of the posterior capsule, i.e. a thickening of the thin transparent membrane that forms the "bag" containing the natural crystalline lens and in which the artificial intraocular lens is placed at the time of surgery. (alfaintes.it)
The particular symptoms depend on the location and density of the opacity, although the most characteristic sign is the opacification of the lens , which should normally be transparent (see the respective types below). (icrcat.com)

The capsule of the lens was pierced with a smaller cut than in conventional cataract surgery - just 1-1.5 mm - and drained of its contents clouding the vision causing cataracts. (wikipedia.org)

We have been performing femtosecond laser cataract surgery in our practice since 2011, first with the LenSx Laser System (Alcon) and later with the Catalys Precision Laser System (Abbott Medical Optics). (crstoday.com)
Based on considerable experience with the technology, it is clear to me that the use of laser cataract surgery provides a number of benefits. (crstoday.com)
A significant advantage of the femtosecond laser-and one that was possibly not anticipated in the early days of laser cataract surgery-is that the incorporated OCT imaging gives the surgeon much more information about the anatomy of the eye, the anterior chamber, and the lens thickness. (crstoday.com)
Knowing how big the crystalline lens is in relation to the anterior chamber helps me prepare for surgery and may eventually allow me to more accurately predict the effective lens position (ELP). (crstoday.com)

An intraocular lens is an artificial lens that is implanted in the eye instead of the lens extracted by cataract surgery. (miyoshi-eye-clinic.com)
The intraocular lens affects the most visible operation (quality of appearance, quality of life) of various surgical items and devices related to cataract surgery. (miyoshi-eye-clinic.com)
Since the single focus intraocular lens has only one focus, it requires eyeglasses frequently after surgery, but the multifocal intraocular lens has more focal points compared to the single focus intraocular lens. (miyoshi-eye-clinic.com)
Multifocal intraocular lenses are expensive due to their own burden, but patients who wish to reduce the frequency of use of eyeglasses after cataract surgery become more and more year by year, and more people who choose multifocal intraocular lens are increasing. (miyoshi-eye-clinic.com)
Because multifocal intraocular lenses are highly functional, precise surgery and examination are required, and depending on the patient's eyes, personality and life, it may be worse than monofocal intraocular lenses. (miyoshi-eye-clinic.com)
If you would like a multifocal intraocular lens during cataract surgery, if you are interested, please do not hesitate to contact your doctor or staff. (miyoshi-eye-clinic.com)

Intraocular pressure (IOP) reduction after cataract surgery has been shown in many studies, and the most recent data indicates that IOP reduction after cataract surgery- is more significant and sustained than previously thought. (keogt.com)
The earliest studies of IOP after cataract surgery showed little if any reduction of IOP. (keogt.com)
Those studies that did stratify patients based on preoperative IOP clearly demonstrated that patients with higher preoperative IOP enjoy the greatest reduction of IOP after cataract surgery. (keogt.com)
However, the early IOP variability following cataract surgery rarely has clinical consequence. (keogt.com)
Many other factors, such as pressurization at the time of surgery, immediate postoperative medications (especially corticosteroid), and viscoelastic type, contribute to short-term IOP fluctuations following cataract surgery. (keogt.com)
Although the physiological reasons for decreased IOP after cataract surgery remain speculative, the facility of outflow is known to increase after cataract surgery. (keogt.com)
[10] Angle width changes less than one would expect following cataract surgery, suggesting improved function of the trabecular meshwork itself rather than improved aqueous access to the trabecular meshwork. (keogt.com)
Three or more different mechanisms may contribute to the observed reduction in IOP after cataract surgery. (keogt.com)
Lens-induced uveitis may develop, and the degree of intraocular inflammation in these patients often is governed by the size of the retained lens fragment, the time since cataract surgery, the patient's individual inflammatory response, and the extent of other intraocular manipulations.
