“…This profile is virtually identical to the pathologic process seen in posterior subcapsular cataracts and in the typical 'pearl' form of PCO. 72 In our second report (Dr Shugar's case), the surgeon could not aspirate the paracentral material attached mostly to the anterior surface of the posterior IOL, which was amorphous, compact and completely acellular. He could only aspirate the pearls and retained/regenerative cortex in the peripheral interface.…”

“…72,73 However, we have recently received in our Center four new pairs of acrylic piggyback lenses explanted because of ILO. Three of these new cases shared the common aspect that exhaustive attempts to clean the interface between the lenses were not performed by the surgeons before explantation, probably because ILO is now a well-known entity.…”

Intraocular lens (IOL) implantation has no doubt been one of the most satisfying advances of medicine. Millions of individuals with visual disability or frank blindness from cataracts had and continue to have benefit from this procedure. It has been reported by ophthalmologists that the modern cataract-intraocular lens (IOL) surgery is safe and complication-free most of the time. This makes the watchword for any cataract surgeon to be 'implantation,' 'implantation,' 'implantation.' In the mid1980s, as IOLs were evolving rapidly, the watchword of the implant surgeon was 'fixation,' 'fixation,' 'fixation.' Most techniques, lenses and surgical adjuncts now allow us to achieve the basic requirement for successful IOL implantation, namely longterm stable IOL fixation in the capsular bag.However despite this advancement some items 'slipped through cracks.' In this article, we would like to alert the reader to a new watchword, namely 'opacification,' 'opacification,' 'opacification.' Here we will be talking about the good, the bad, and the ugly. Examples of the 'good' include the recent successes now being achieved in reducing the incidence of posterior capsule opacification. Examples of the 'bad' include various proliferations of anterior capsule cells, problems caused by silicone oil adherence to IOLs and problems with piggyback IOLs. The 'ugly' include the sometimes striking and often visually disabling opacifications occurring on and within IOL optics, both on some modern foldable IOLs as well as a poly(methyl methacrylate) (PMMA) optic degradation occurring with some models a decade or more after implantation.

“…The technique was then extended to correct pseudophakic spherical 2 or astigmatic 3,4 refractive errors. Because of the position of both IOLs in the capsular bag, complications such as interlenticular opacification [5][6][7] and changes in refractive results due to shift of the second IOL 8,9 were observed. Thus, the authors recommended implanting the second IOL in the ciliary sulcus.…”

DESIGN: Case series. METHODS:In pseudophakic eyes, the axial length (AL) and horizontal WTW were measured by the IOLMaster device. Cross-sectional images were obtained with a 50 MHz ultrasound biomicroscope on the 4 meridians: vertical, horizontal (180 degrees), temporal oblique, and nasal oblique. Sulcusto-sulcus (STS), angle-to-angle (ATA), and sclera-to-sclera (ScTSc) diameters were measured. The IOL optic diameter (6.0 mm) served as a control. To test reliability, optic measurements were repeated 5 times in a subset of eyes. RESULTS:The vertical ATA and STS diameters were statistically significantly larger than the horizontal diameter (PZ.0328 and PZ.0216, respectively). There was no statistically significant difference in ScTSc diameters. A weak correlation was found between WTW and horizontal ATA (r Z 0.5766, P<.0001) and between WTW and horizontal STS (r Z 0.5040, PZ.0002). No correlation was found between WTW and horizontal ScTSc (r Z 0.2217, PZ.1217). CONCLUSIONS:The sulcus anatomy had a vertical oval shape with the vertical meridian being the largest, but it also had variation in the direction of the largest meridian. The WTW measurements showed a weak correlation with STS. In pseudophakic eyes, Soemmerring ring or a bulky haptic may affect the ciliary sulcus anatomy.

“…Na veterinária, são utilizadas lentes intra-oculares (LIOs), num esforço de maximizar a recuperação visual, com restauração da emetropia (Miller e Murphy, 1995). A implantação de duas ou mais lentes intraoculares na câmara posterior, polipseudofaquia ou em piggyback, é realizada para fornecer adequada correção óptica a pacientes pseudofácicos que requeiram alto poder de refração de lente intra-ocular, bem como para alcançar emetropia em olhos extremamente curtos (Findl et al, 1999;Gayton et al, 2000).…”

RESUMOAvaliou-se o erro refracional em 40 cães submetidos ou não à facectomia por facoemulsificação, por meio de retinoscopia com luz em faixa. Distribuídos em quatro grupos de 10 animais cada, foram designados por cães fácicos, cães afácicos (CA), cães pseudofácicos com implante de duas lentes intra-oculares em piggyback (PP) e cães pseudofácicos com implante de uma lente intra-ocular veterinária de 41D (PL). As avaliações foram realizadas por ceratometria, ecobiometria ultra-sônica e retinoscopia. A média da curvatura corneana foi de 40,46±2,44D. O poder dióptrico obtido por retinoscopia foi de 18,50D no grupo CA, 5,25D no grupo PP e 2,00D no grupo PL. A retinoscopia com luz em faixa constituiu um método eficaz para avaliar a refração ocular em cães, mas foi dificultada quando da presença de opacidade de meios oculares. Todos os animais apresentaram-se hipermétropes, em diferentes graus; o astigmatismo ceratométrico cirurgicamente induzido foi discreto. Palavras-chave: cão, retinoscopia, fácicos, afácicos, pseudofácicos ABSTRACT The refraction error in dogs submitted or not to phakectmy, by phakoemulsification by streak retinoscopy was evaluated. Forty dogs were distributed in four groups of 10 animals each, and were designated by phakic, aphakic (AD), pseudo-phakic with two piggyback intraocular lenses (PD), and pseudo-phakic with one intraocular 41D veterinary lens implant (LD
