Authors relate their experience about clear crystalline lens surgery for high myopia, as practiced on 50 consecutive strongly short-sighted patients (beyond -8D). They analyze the collected data and lay down the interest of such a surgery.
It’s a retrospective study, based on 50 short-sighted (> -8 D) patients, operated on by the same surgeon throughout the last 3 years. After topical anaesthesia, with a 2,8 mm corneal incision phakoemulsification was performed (Storz Première, Bausch and Lomb, Rochester, NY), using a diving-and-conquer technique. All the eyes had a foldable soft hydrophilic IOL implanted. (BigBag IOL, lab IOLTECH, France). Post-surgery treatment was identical for every patient. Patients were reviewed after one month and their acuity level measured and adjusted in spherical equivalent.Authors analyze refraction and visual acuity level, both before and after surgery. They also analyze the characteristics of patients who were operated on, pain, post-surgery events and possible reported complications.
Our patients were quite young the age average was 59,7 +/- 6,7 years, with a 60 median. Pre-surgery refraction average was -15,40 +/- 4,60 D, adjusted in spherical equivalents with a -14,75 median, 11 patients (22%) had a refraction over -20 D. To considered visual acuity we noted that pre-surgery average acuity was 0,07 +/- 0,14.All patients were controlled one month after surgery and refraction average was -0,26 +/- 1,04, with a -0,25 median. 11 patients (22%) were emmetrops, 39 patients (78%) had a refraction comprised between -1 et +1 D, and average visual acuity was 0,35 +/- 0,28. 35 patients (70%) had a post-surgery visual acuity superior or equivalent to 0,4.In post-surgery all patients were painless, and no complication was found after a 3 years follow up.
In order to avoid resorting to potentially detrimental to corneal endothelial cells implants, authors recommend refractive purpose clear crystalline-lens surgery be used for high myopia. Our results show that this technique seems to be sure, re-usable and to entail good and long-lasting visual and refractive results, with neither retinal nor corneal notable complications.
