Finally, large incisions require numerous sutures, and these can also lead to increased astigmatism. SILICONE LENSES Even though Kelman introduced the phaco technique with incisions of approximately 3 mm in the early 1970s, the surgical procedure could only be completed with an enlargement of the incision to 6 to 8 mm to allow the introduction of the IOL. In the early 1980s, Dr. Thomas Mazzocco recognized that in cases of severe myopia, when implantation of an IOL was not indicated, the surgical procedure terminated with removal of the cataract through the 3-mm phaco incision.
376. The increase in the refractive power is indicated by the warmer colors. 00 mm from the center. Consequently, the choice of an aspheric IOL to compensate corneal aberrations and achieve the best visual acuity (BCVA) and the best contrast sensitivity is determined by careful study of the corneal HOA and its spherical aberration. Presently, the FDA has approved 3 lenses for correction of positive spherical aberrations: Tecnis Z9000 (AMO), SofPort AO (B + L), and AcrySof IQ (Alcon). They each have a different strategy for the correction of spherical aberration.
0 for all of the models; the shape of the optic changes—the AR40M (an IOL with a negative dioptric power) is a meniscus; the other 2 models are classical biconvex lenses. 0 mm. The vaulting of the loops is 5 degrees, the same as for the other models of 3-piece IOLs discussed previously. The ZA9003 IOL differs from the previous model because of the aspheric anterior surface of the optic. 0 mm) is always made of hydrophobic acrylic. 0 D. The ZA9002 has a silicone optic; it also has an aspheric anterior surface, 3-piece with PMMA haptics.
