The first IOL successfully implanted in humans was done in 1949 with a polymethylmethacrylate (PMMA) IOL. New biocompatible materials such as hydrophilic acrylic, hydrophobic silicone, hydrophobic acrylic, among others, were developed, each with different advantages and disadvantages. Hydrophilic acrylic has a greater risk of posterior subcapsular opacity and dystrophic calcification, hydrophobic silicone opacifies in the presence of liquid silicone in the posterior segment, hydrophobic acrylic has more risk of glistening. The latter is the most widely used IOL in Chile due to its flexibility, low risk of dystrophic calcification and low risk of posterior subcapsular opacity. The greatest advances were made with new IOL designs. The traditional IOL is the monofocal IOL that later incorporates toricity. Multifocal diffractive bifocal and then trifocal IOLs appear giving spectacle independence but dysphotopsia. The Extended Depth of Focus (EDOF) technology allows exploring new optical properties, providing intermediate functional vision with minimal dysphotopsia. Today these characteristics are combined and we have a wide range of IOLs with different functionalities. This review aims to describe the performance of the different materials and designs, especially the most representative ones in our country. It also provides tools to define the most suitable IOL model for each patient and gives suggestions on formulas to calculate the spherocylindrical power in some special situations. Finally, a brief explanation of the future perspectives with the new accommodative IOLs under development.</p></div>","PeriodicalId":31544,"journal":{"name":"Revista Medica Clinica Las Condes","volume":"34 5","pages":"Pages 359-369"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49904292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article presents the case of a patient with TBD, who debuted with adenomegaly in the right inguinal región. Histologically, a granulomatous process, with central necrosis was found. Since TB was not taken into account in differential diagnoses and samples were not sent for culture, the opportunity of an early diagnosis was missed resulting in the dissemination of the bacillus, with the appearance of tuberculous peritonitis and tuberculous gumma. Endometrial involvement may have been the primary focus. The patient did not present clinical or radiological lung involvement, and was HIV negative.

These tumors grow slowly, in the long term eventually compressing the optic nerve and other structures such as extra-ocular muscles and the eyeball. This translates into exophthalmos and chronic vision loss that can lead to blindness in the affected eye. The adequate clinical interpretation of this medical condition, associated with the use of neuroimaging, mainly computed tomography and magnetic resonance imaging, allow us to make a timely diagnosis. Treatment is primarily based on fractionated stereotactic radiotherapy when the tumor is advancing and the focus is on vision preservation. Surgery is indicated when vision has already been significantly lost or there is a threat of invasion of the optic chiasm. Chemotherapy treatment options are still under study. The vital prognosis of this pathology is good, but functionally it can leave significant sequelae depending on the behavior of the tumor, as well as how early we make its diagnosis.</p><p>The objective of this article is to comment on the current state of what is known about orbital meningiomas, their diagnosis and existing therapeutic alternatives.</p></div>","PeriodicalId":31544,"journal":{"name":"Revista Medica Clinica Las Condes","volume":"34 5","pages":"Pages 322-326"},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49904290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
