The lensectomy refractive cataract surgery is now able to correct vision defects such as myopia, hyperopia, astigmatism and even presbyopia. But what do you expect this intervention? And for those indicated? The expert in Ophthalmology of the ' Istituto Clinico San Carlo , Dr.. Renato Tanzarella, explains what it is
What problems can be solved with lensectomy refractive?
The lensectomy is primarily useful for the removal of cataracts, or for the lens opacities mainly due to the patient's age. In addition, the many lensectomy is useful for correcting refractive defects, including, myopia, hyperopia, astigmatism and presbyopia.
As the surgeon works of lensectomy?
The lensectomy is a microsurgical intervention: runs to Limbus, ie to the extremes of the cornea, through two small incisions that do not exceed 2 mm width. Through these two incisions it enters the eye, by means of the phacoemulsificator irrigant and a cannula which serves to drain, to irrigate the eye, to maintain the spaces. Before these two instruments, it introduces a viscoelastic substance that allows to perform the capsulotomy, namely the removal of the front cover of the capsule. Then you run a emulsification and aspiration of the masses catarattose. After complete aspiration, in which a residual perfectly transparent capsule, the same is introduced within the IOL, commonly called artificial lens.
For such patients is indicated lensectomy?
The lensectomy an intervention is mainly indicated for the removal of cataracts, but this method also serves to correct, as already mentioned, many defects of a refractive type, such as myopia, hyperopia, and astigmatism. In fact, while a time were used of monofocal lenses, which corrected the defect only for a distance, now you can introduce the lenses, toric lenses calls or at a different dioptric power, which are able to correct these refractive defects by the use of multifocal lenses .
Lensectomy: what are the advantages and disadvantages?
The advantages of lensectomy are, the removal of the cataract, cataract, and then allow the subject to be able to clearly see and especially, in younger subjects, correcting the defects already mentioned, such as myopia, hyperopia and astigmatism.Postoperative disadvantages, however, are modest: eye inflammation, treatable with medical therapy, or macular edema, a complication, however, very rare.
