He also sits on several clinical advisory panels and has developed various surgical instruments to aid in cataract surgery. Shatz has operated on leaders in the entertainment, sports, and business world, and has developed techniques and instruments for use in lens surgery. Shatz often teaches his surgical techniques to other ophthalmologists in the country, and is frequently called upon by his colleagues to treat their most difficult cases.

A prototype of a novel dual-mode, accommodating-disaccommodating intraocular lens with zonular capture haptics has been fabricated successfully.

He works in Sunrise, FL and specializes in Ophthalmology. Shatz is affiliated with Plantation General Hospital and Broward Health Coral Springs.

Shatz graduated from the Medical College of Georgia School of Medicine in 1995.

Section 4 – Lens surgery 315 Chapter 42 – Indications for Lens Surgery and Different Techniques HARRY B. Therefore, in developed societies where surgical technology is advanced, perceived economic conditions may be the factors that determine the prevalence and definition of “cataract blindness” for a population, and this changes as conditions change. In Europe, Japan, and the United States, where phacoemulsification and foldable lens implantation are widely standard, the only ocular indication for planned nuclear delivery may be an advanced nucleus that is too hard to be emulsified safely.

GRABOW KEY FEATURES • Lens surgery is the most common eye operation. In many underdeveloped nations, the prevalence of cataract blindness is determined by the availability of care. Corneas at risk for developing irreversible edema, such as those with low endothelial cell counts or guttate dystrophy, may be relative indications for nuclear delivery.

However, with the rapid acceptance, by both surgeons and patients, of corneal refractive surgery, particularly LASIK, and with the prevalence of ametropia far exceeding the prevalence of cataract in the world population, it may be only a few years before the number of cataract operations is exceeded by the number of refractive procedures. Same corneal, cataract, and capsular indications as nuclear delivery B. Traditionally, intracapsular extraction involved removal of the complete intact lens through a large incision measuring 11–16? Later, implantation of a PMMA IOL, either primarily or secondarily, rendered these eyes pseudophakic, with both procedures requiring sutures.

Shatz is an assistant clinical professor at Philadelphia College of Osteopathic Medicine.These are relatively new indications, only decades old, and they may or may not be considered pathological conditions. The decision to remove a cataract in an otherwise healthy eye usually depends on the cataract’s impact on the visual function of the eye and the impact of that level of visual impairment on the person’s life. It has been observed that with certain phacoemulsification techniques, the longer the duration of ultrasound, the greater the loss of endothelial cells ( Fig. In addition, the closer the emulsification process is to the cornea, the more cells are lost ( Table 42-2 ), and corneas with guttatae lose more cells than normal corneas do ( Table 42-3 ). Prediction of visual function after cataract surgery: a prospectively validated model. In some settings, surgery for such conditions is considered controversial, if not contraindicated. In healthy eyes whose only disorder is cataract, the presumed outcome after uncomplicated surgery is better vision than before surgery. Therefore, the degree of nuclear sclerosis and the health of the cornea are indications for protective ophthalmic visco-surgical devices and for phacoemulsification as far away from the cornea as possible. Nd: YAG laser capsulotomy/capsulectomy Acry Sof MA60AC and AMO, Sensar AR40e) and in silicone (AMO, Clariflex Band Pharmacia C911). However, the ophthalmic subspecialty of refractive surgery gained a secure foothold in the late 1990s, and refractive lens surgery is rapidly becoming a common tool in the armamentarium of both cataract and refractive surgeons. Indeed, in the most technologically advanced societies, patients are requesting emmetropia, and even restoration of accommodation. When phacoemulsification was originally performed in the anterior chamber and in the iris plane, high-risk corneas and dense nuclei were considered contraindications, and nuclear delivery was recommended. The square edge has been shown to be a physical barrier to the central posterior migration of LECs.[23] Zonular Surgery The preceding discussion of the surgical management of the lens capsule concentrated on endocapsular techniques and management of the viable LECs on the interior surface of the lens capsule. The lens plays such a significant role in the visual refractive system of the eye that many, if not all, of the medical conditions of the lens also interfere with its optics. In such “healthy” eyes, cataract surgeons experience a rate of intraoperative and postoperative complications of less than 2% or, conversely, an uncomplicated rate of 98%. However, long ultrasound times have been shown to be well tolerated when the ultrasonic energy is confined to the capsular bag. The discussion would be incomplete if it did not address a significant, difficult, new area of capsular surgery that deals with an abnormality of the exterior capsule—management of the weak or partially absent zonule. Improved visual function and attenuation of declines in health-related quality of life after cataract extraction.

Medical indications arise from pathological states of the lens of varying causes, usually related to lens clarity, lens position, or other lens-related conditions, such as inflammation or glaucoma. [4] However, in structured economic societies, third-party payers and governmental regulatory agencies are not interested in the results of these sophisticated methods of analyzing loss of lens function; they are more interested in how the loss of lens function interferes with life functions. However, LENS REMOVAL TECHNIQUES: OCULAR INDICATIONS I. The nucleus may be separated concentrically, delivering the smallest endonucleus separately from outer layers of epinucleus. mm sutureless scleral incision using side-port irrigation through a chamber maintainer to hydroexpress the nuclear components, which delaminate as they pass through the incision. [26] True intraocular phacosection involves bisecting or trisecting the nucleus by instrumentation, achieving geometrical nuclear division in the anterior chamber.
