We describe a surgical technique for secondary stabilization of a bag-in-the-lens intraocular lens (BIL IOL) using 2 modified bean-shaped ring segments in cases of zonular dehiscence associated with pseudophakodonesis. The first modified bean segment is anchored in the sulcus with a suture to the sclera in the area of maximum zonular dehiscence, and the second segment is implanted in the opposite sulcus area. Both segments are placed in the BIL IOL interhaptic groove. The segments stabilize and center the BIL IOL by creating an artificial zonule that provides the necessary extra support for the IOL...

PURPOSE: To compare the accuracy of axial length vergence formulas versus refractive vergence formulas for secondary intraocular lens (IOL) implantation in pediatric aphakia. METHODS: This retrospective comparative study, evaluated 31 eyes of 31 patients aged ≤3.5 years, who had undergone secondary IOL implantation. The median absolute error (MedAE) was compared between axial length vergence formulas (Hoffer Q, Holladay I, SRK II, and SRK/T) and refractive vergence formulas (Lanchulev, Holladay R, Mackool, and Khan) as well as between formulas within the same vergence...

Intraocular lymphoma (IOL) is a rare lymphocytic malignancy which contains two main distinct forms. Primary intraocular lymphoma (PIOL) is mainly a sub-type of primary central nervous system lymphoma (PCNSL). Alternatively, IOL can originate from outside the central nervous system (CNS) by metastasizing to the eye. These tumors are known as secondary intraocular lymphoma (SIOL). The IOL can arise in the retina, uvea, vitreous, Bruch's membrane and optic nerve. There are predominantly of B-cell origin; however there are also rare T-cell variants...

PURPOSE: To compare the cyto- and chemokine profiles in the aqueous humor of PEXS eyes in the absence or presence of secondary glaucoma with or without luxation of the intraocular lens (IOL). METHODS: Samples of aqueous humor were collected intraoperatively from 20 healthy controls and from 73 eyes with PEX-syndrome, which was manifested in the absence of any other local or systemic desease. The latter group was sub-devided into eyes with an early form of PEX-syndrome in the absence of complications (PEX, n = 33), those with a late form of PEX-syndrome and glaucoma (PEXG, n = 30), and those with a late form of PEX-syndrome with luxation of the IOL that required surgery (PEXL, n = 10)...

Ocular trauma can lead to severe visual impairment and morbidity, depending on the anatomical structures affected. The main causes of ocular trauma include foreign bodies, impact by an object, falls, and chemicals. Most ocular traumas occur in children or young male adults. A meticulous slit lamp examination is crucial for assessing all anatomical structures. Trauma to the crystalline lens can result in dislocation, an intralenticular foreign body, cataract, fragmentation, and capsular breach. An intraocular lens (IOL) can endure subluxation or luxation under the conjunctiva, into the anterior chamber or the vitreous, or can be extruded...

AIM: To evaluate the rotational stability and visual outcomes of a single-piece hydrophilic acrylic toric intraocular lenses (IOL) over a 1.5-year follow-up period. Data from the 6-month follow-up study have been previously reported. METHODS: Forty eyes of 26 cataract patients (mean age: 72.8±7.9y) with pre-existing corneal astigmatism of 1.0 to 2.6 D were enrolled in the study. Mean axial length was 23.17±0.88 mm. Main outcome measures after implantation of the Torica-aA IOL (HumanOptics) were IOL rotational stability, subjective refraction, astigmatism correction, uncorrected and corrected distance visual acuity (UDVA, CDVA)...

Copepods belonging to the Oncaeidae family are commonly and abundantly found in marine zooplankton. In the Mediterranean Sea, forty-seven oncaeid species occur, of which eleven in the Gulf of Naples. In this Gulf, several Oncaea species were morphologically analysed and described at the end of the XIX century by W. Giesbrecht. In the same area, oncaeids are being investigated over seasonal and inter-annual scales at the long-term coastal station LTER-MC. In the present work, we identified six oncaeid species using the nuclear ribosomal internal transcribed spacers (ITS rDNA) and the mitochondrial cytochrome c oxidase subunit I (mtCOI)...
