Crystalline lens is an intraocular structure that in its youth allows clear vision at all distances, from far to near vision, even in intermediate distances. However, the accommodation capability of the crystalline lens is reduced with the age […]
The cornea is a structure formed by two optical surfaces. Correct corneal morphology allows visual transparency and provides corneal dioptric power. However, in some corneal pathologies or ectasias such as keratoconus, the corneal integrity is compromised. In such […]
Inside of the eyeball, the crystalline lens allows clear vision at all distances from near to far vision during the youth. However, with age, around 60 years old due to internal changes which occurring in its morphology, the […]
Inside of eyeball, there is a natural lens, called crystalline lens that during the youth is transparent and allows clear vision at all distances. However, over the years, due to various changes that happen in the […]
Durante los días 7 y 8 de abril a tenido lugar el curso ARI—UMH 2017 de “METODOLOGÍA CLÍNICA Y PRÁCTICA EN CIRUGÍA REFRACTIVA DE CATARATAS Y CÓRNEA” en Alicante, concretamente en el auditorio del Centro Vissum. Este curso monográfico tiene acreditación universitaria y ha sido apoyado por la Universidad Miguel Hernández de Alicante. En estas [...]
In a consultation of ophthalmology, corneal topography is one of the devices more used to know the corneal morphology. Its analysis is very important because provide information about the curvature and potency of the cornea, among other parameters […]
FemtoLASIKLaser-Assisted In Situ Keratomileusis (LASIK) is one of the surgical ambulatory procedures most performed worldwide for the correction of myopia, hyperopia or astigmatism. In the surgery it is necessary to lift a corneal lenticule with a femtosecond […]
Presbyopia is a natural condition that induces difficulty to read in near distances in patients with age over 40 years approximately. The gradual loss of accommodative capacity to focus near objects in presbyopic patients is due to variations in the crystalline lens, ciliary muscle as in zonular […]
The crystalline lens by means of variations in his amplitude of accommodation allows see clear at all distances, as well it provides transparency in his youth. Nevertheless, with the age from 45 years approximately a loss in the ability of accommodation that difficult the observation […]
Cataract surgery is one of the most common surgical interventions worldwide to restore vision with a high success rate and patient cataract surgery satisfaction. In spite of the improvements made on this procedure, cataract surgery is not fully exempt from risks. Precisely, recent advances with the introduction of minimal incision cataract surgery (MICS)[…]
