Dear Sir: I would like to congratulate Drs Pareja-Esteban J et al for their article titled “Brown-McLean syndrome and refractive phakic anterior chamber intraocular lenses” (1). The purpose of this letter is to clarify the concept of the Brown-McLean syndrome or circumferential peripheral corneal edema which appears as idiopathic due to a number of cases with anterior chamber refractive intra-o...
The primary goal of refractive surgery is the smallest residual refractive error and preserved contrast sensitivity with the same visual capacity under bright and dim illumination. Corneal refractive surgery cannot correct very high ametopias; from -10 to -14 D is the limit of myopia correction in the cornea and from +4 to +6 D, the limit of hyperopia correction. Intraocular refractive surgery ...
Causes of Explantation of Phakic Intraocular Lenses We read with interest the article by Alió et al.1 on phakic intraocular lens (PIOL) explantation in the January issue. There is an ongoing debate about the long-term safety of PIOLs, especially angle-supported lenses.2 In late 2014, Alcon Laboratories, Inc. discontinued production of the AcrySof CACHET Phakic Lens (Alcon Laboratories, Inc., Fo...
OBJECTIVE To evaluate safety, efficacy, predictability, stability, complications, and patient satisfaction after implantation of Artisan toric phakic intraocular lenses (TPIOLs) for the correction of myopia or hyperopia with astigmatism. DESIGN Prospective, nonrandomized, comparative (self-controlled) multicenter trial. PARTICIPANTS Seventy eyes of 53 patients (mean, 35 years; range, 22-59 ...
The occurrence of haemolytic glaucoma in phakic eyes due to ghost cells has not previously been reported. Three cases of haemolytic glaucoma occurring over two years after massive vitreous haemorrhage in patients with an intact lens iris diaphragm are described. In one case there was histological confirmation of the presence of ghost cells in the anterior chamber. The mechanism proposed for the...
To the Editor: We read with interest the article by Cakir and Utine1 regarding the results of combined intracorneal ring (KeraRing; Mediphacos Ltd, Belo Horizonte, Brazil) and anterior chamber, iris-fi xated, phakic intraocular lens (IOL) (Artisan/Artifl ex; Ophtec BV, Groningen, The Netherlands) implantation in patients with keratectasia, which appeared in the February 2011 issue of the Journa...
