SMILE With Low Energy Levels: Assessment of Early Visual and Optical Quality Recovery.

Purpose: To assess early visual and optical quality recovery according to preoperative refraction after small incision lenticule extraction (SMILE) at low energy level for myopia and myopic astigmatism treatment.

Methods: This prospective study included 101 eyes of 101 patients separated into three groups: low myopia (30 eyes), with a mean spherical equivalent (SE) of -2.13 ± 0.

Lower Energy Levels Improve Visual Recovery in Small Incision Lenticule Extraction (SMILE).

Purpose: To compare the visual outcomes with energy close to the plasma threshold and energy at the standard set-up in small incision lenticule extraction (SMILE).

Methods: This retrospective, non-randomized, consecutive clinical case series included 486 eyes of 243 patients who underwent SMILE and were subdivided into two groups depending on the laser energy settings: the standard energy group (164 eyes) using a laser cut energy index of 36 (180 nJ), and the plasma threshold group (322 eyes) using a cut energy index of 20 (100 nJ, close to plasma threshold). A spot spacing of 4.

Preliminary Evidence of Successful Enhancement After a Primary SMILE Procedure With the Sub-Cap-Lenticule-Extraction Technique.

Purpose: To describe a modified small incision lenticule extraction (SMILE) procedure called sub-cap-lenticule-extraction (Sub-Cap-LE) for refractive enhancement after SMILE.

Methods: Case report.

Results: A 53-year-old woman who underwent bilateral SMILE for moderate myopia complained of blurred vision at distance postoperatively.

Histologic and ultrastructural characterization of corneal femtosecond laser trephination.

Purpose: The purpose of this study was to evaluate the quality of femtosecond laser corneal trephination in eye bank eyes by histologic and ultrastructural investigation.

Methods: We performed Z-shaped, tophat-shaped, and mushroom-shaped trephinations of swelled corneas from eye bank eyes using an Intralase FS60 system. The corneoscleral discs were fixed immediately after the laser procedure without removing the buttons.

In situ monitoring of second-harmonic generation in human corneas to compensate for femtosecond laser pulse attenuation in keratoplasty.

The application of femtosecond lasers in corneal transplant surgery requires high pulse energies to compensate for the strong optical scattering in pathological corneas. However, excessive energies deteriorate the quality of the incisions. The aim of this study is to demonstrate the dependence of side effects on local radiant exposure, numerical aperture, and tissue properties, to quantify the penetration depth of the laser for individual corneas, and to provide a method for optimizing the energy in the volume of the cornea.

Cataract formation with a primary iris stromal cyst.

An 11-year-old boy was diagnosed with a primary acquired iris stromal cyst. A 5-year follow-up showed growth of the cyst with visual impairment. An inferior iridectomy was performed including the whole cystic lesion.

Malignant glaucoma induced by a phakic posterior chamber intraocular lens for myopia.

A 23-year-old woman with -14.00 diopters of myopia requested emmetropia for professional reasons. An ICM 130 V2 myopic phakic intraocular lens (IOL) (Staar Surgical AG) was implanted in the posterior chamber.
