“…Induction of monovision using laser vision correction (LVC) is the simplest approach to laser presbyopia correction; it has a 90% success rate, although there are disadvantages, including reduced visual acuity in darkness, loss of contrast sensitivity, reduction of stereopsis, and intermediate vision reduction.

Presbyopia is the primary cause of reduction in the quality of life of people in their 40s, due to dependence on spectacles. Therefore, presbyopia correction has become an evolving and rapidly progressive field in refractive surgery. There are two primary options for presbyopia correction: the dynamic approach uses the residual accommodative capacity of the eye, and the static approach attempts to enhance the depth of focus of the optical system. The dynamic approach attempts to reverse suspected pathophysiologic changes. Dynamic approaches such as accommodative intraocular lenses (IOLs), scleral expansion techniques, refilling, and photodisruption of the crystalline lens have attracted less clinical interest due to inconsistent results and the complexity of the techniques. We have reviewed the most popular static techniques in presbyopia surgery, including multifocal IOLs, PresbyLASIK, and corneal inlays, but we should emphasize that these techniques are very different from the physiologic status of an untouched eye. A systematic PubMed search for the keywords “presbylasik”, “multifocal IOL”, and “presbyopic corneal inlay” revealed 634 articles; 124 were controlled clinical trials, 95 were published in the previous 10 years, and 78 were English with available full text. We reviewed the abstracts and rejected the unrelated articles; other references were included as needed. This narrative review compares different treatments according to available information on the optical basis of each treatment modality, including the clinical outcomes such as near, intermediate, and far visual acuity, spectacles independence, quality of vision, and dysphotopic phenomena.

A healthy infant girl presented with bilateral 1-mm anterior polar cataracts. Initial monitoring every 2 to 3 months was recommended, but she did not return until she was 16 months old, at which point the cataracts had prominent pyramidal growth with a significant cortical component (Figure). Her visual acuity was 0.64 cycle/cm OD using Teller acuity cards, and she would only fix and follow OS. The remainder of her examination was unremarkable, including B-scan ultrasonography of the posterior segment. She underwent lensectomy/anterior vitrectomy in each eye and used aphakic con-tact lenses. She was 3 years old at her last visit and had inconsistent follow-up and poor compliance with amblyopia management. Her visual acuity was 20/60 OD and 20/250 OS, complicated by a sensory left esotropia.Anterior pyramidal cataracts have been reported as unilateral or bilateral presentations at birth but may progress from typical polar opacities. There are no systemic associations. 1-3 Rarely, a spontaneous dehiscence of the pyramid into the anterior chamber may occur. 4,5
