Purpose: To compare by optical microscopy, tissue reaction caused by the Alloplant ™ to conjunctiva and backs of 24 rabbits. Methods: All rabbits underwent implantation of Alloplant ™ on the inner third of the lower eyelid, replacing the tarsal conjunctiva of one eye. After thirty days six rabbits (Group I) were sacrificed and lower eyelids of both sides and a back fragment (control) routed to optical microscopy. After sixty days six rabbits (group II) were sacrificed and their eyelids and […]

Objetivo: Avaliar a introdução do laser de femtossegundo (FSL) para realizar etapas fundamentais da cirurgia de catarata tradicional e as dificuldades e segurança desta nova tecnologia na rotina de um centro cirúrgico no Brasil. Métodos: Um estudo retrospectivo foi realizado com os primeiros casos operados em um único centro usando a plataforma de laser LenSx/Alcon, sendo utilizado lentes de contato gelatinosa na interface do paciente. Todos os pacientes foram submetidos a uma avaliação pré-operatória detalhada. Capsulotomia anterior, fragmentação nuclear e […]

Objective: To evaluate the introduction of the femtosecond laser (FSL) to perform the key steps of the traditional cataract surgery process and the operational difficulties and safety of this new technology during routine use in an operating room in Brazil. Methods A retrospective study was conducted using the first cases operated on at a single center using the laser platform LenSx/Alcon with a soft contact lens patient interface.All patients underwent a detailed preoperative assessment.The anterior capsulotomy, nuclear fragmentation, and corneal […]

Purpose: To evaluate the changes of corneal biomechanical after femtosecond laser – assisted cataract and to compare the parameters derived by Corvis ST between standard phacoemulsification and femtosecond laser – assisted in cataract surgery Methods: This is a prospective study. 151 eyes of 127 patients were under went cataract surgery. 75 eyes of 65 patients were with femtosecond laser–assisted (FS)(Alcon Len Sx, Aliso Viejo,USA) and 76 eyes of 62 patients with standard phacoemulsification (SP) (Alcon Infinit, Fort Worth, USA). Lens […]

Objective: To determine the measurements of interpupillary distance (IPD) and ocular convergence in the presbyopic population with corneal reflex pupillometer. Methods: 160 subjects (66 males and 94 females) aged 41 to 85 years have their measurements of IPD done – far and near – by CRP method. Results: The mean age was 55.9 ± 11.5 years; the average IPD was 65.02 ± 2.78 and 62.47 ± 3.15 mm for male and female respectively. Also, the average convergence was 5.00 ± […]

The propose of this article is presenting a case report of Synchisis scintillans of the anterior chamber in an infant patient without any elucidation. The patient’s initial complaint was “strabismus since birth”. There was not found any other personal or family abnormalities. On examination: OS: Esotropia maintained, horizontal nystagmus, microphthalmia and leukocoria. OD: no abnormalities. Ultrasonography (USG) OS: reduction of the axial length, retinal applied and hyperechoic vitreous. Raised hypotheses were persistence of hyperplastic primary vitreous, congenital cataract and retinoblastoma, […]
