A Prospective Study

Background/Aim. Photorefractive keratectomy (PRK), after laser in situ keratomileusis (LASIK), is commonly performed refractive surgical method worldwide. The aim of this study was to examine the effectiveness and safety of PRK in correction of various strengths of myopia and to assess how much corneal tissue is being removed with one diopter sphere (Dsph) correction by using different optical zones (OZ). Methods. A prospective study with a follow-up period of 6 months included 55 patients of which 100 myopic eyes were treated by PRK method (one eye was included in 10 patients). Myopic eyes with a preoperative best corrected visual acuity (BCVA) = 1.0 (20/20) were analysed. In order to assess the effectiveness of PRK operated myopic eyes were divided into four groups according to the dioptric power: 1)? -1.75 Dsph (n = 26); 2) from -2 to -3.75 Dsph (n = 44); 3) from -4 to -6.75 Dsph (n = 23), and 4) ? -7 Dsph (n = 7). Myopic eyes with preoperative BCVA ? 0.9 (amblyopic eyes) were excluded from the study, as well as eyes with astigmatism > -1.5 Dcyl. To assess the effectiveness of PRK we examined the percentage of eyes in the mentioned groups, which derived uncorrected visual acuity (UCVA) 6 months after the intervention to the following: a) UCVA = 1.0 (20/20) and b) UCVA ? 0.5 (20/40). To assess the safety of PRK we examined the frequency of intraoperative and postoperative complications. To estimate how much corneal tissue was removed with one Dsph correction by using different OZ, we used preoperative and postoperative (after 6 months) central pachymetry values expressed in ?m and volume of cornea (central 7 mm) expressed in mm?. In that sense, we used only the myopic eyes with clear preoperative spherical refraction. The total number of these eyes was 27, of which 16 eyes were treated using a 6.5 mm OZ and 11 eyes using a 7 mm OZ. Results. Refractive spherical equivalent (RSE) for all eyes was in the range from -0.75 to -8.75 Dsph, and preoperative mean value of RSE with standard deviation (mean RSE ? SD) was -3.32 ? 1.83 Dsph. Six months after PRK, 91% of eyes had UCVA = 20/20, and 99% of eyes had UCVA ? 20/40. In the first group (? -1.75 Dsph) preoperative mean RSE ? SD was -1.34 ? 0.32 Dsph, six months after PRK, 96% of eyes had UCVA = 20/20, and 100% of eyes had UCVA ? 20/40. In the second group (from -2 to -3.75 Dsph) preoperative mean RSE ? SD was - 2.95 ? 0.57 Dsph, six months after PRK, 89% of eyes had UCVA = 20/20, and 100% of eyes had UCVA ? 20/40. In the third group (from -4 to -6.75 Dsph) preoperative mean RSE ? SD was - 4.93 ? 0.70 Dsph, six months after PRK, 100% of eyes had UCVA = 20/20. In the fourth group (? - 7 Dsph) preoperative mean RSE ? SD was -7.71 ? 0.67 Dsph, six months after PRK, 57% of eyes had UCVA = 20/20, and 86% of eyes had UCVA ? 20/40. There were no intraoperative complications while postoperative complications occurred in 2 patients - in both cases in one eye (2%). In that cases, epithelial defects were detected. In the group of eyes that were treated by 6.5 mm OZ mean RSE ? SD was -2.45 ? 0.99 Dsph, the ablation depth per 1 Dsph was 17.54 ? 5.58 ?m and ablated volume of central 7 mm cornea by 1 Dsph was 0.43 ? 0.18 mm?. In the group of eyes that were treated by 7 mm OZ mean RSE ? SD was -3.32 ? 2.26 Dsph, the ablation depth per 1 Dsph was 23.73 ? 6.91 ?m and ablated volume of central 7 mm cornea by 1 Dsph was 0.61 ? 0.31 mm?. Conclusion. PRK is effective and safe refractive surgical method for correcting myopia up to -8 .75 Dsph. OZ size is the main factor determining the depth of the excimer laser ablation of the corneal tissue volume consumed by 1 Dsph. Higher OZ value determines higher consumption of cornea tissue.

Abstract Background The aim of this study is to evaluate the safety and efficacy of transconjunctival cryo-assisted orbitotomy for extraction of intraconal cavernous hemangioma. Methods The study was performed at the Mansoura ophthalmic center, Mansoura University, Egypt from May 2015 to August 2018. It included 18 patients with orbital intraconal cavernous hemangioma. In all cases, preoperative orbital MRI with contrast was performed, transconjunctival approach was used and cryo-assisted extraction of the lesion was performed. Cases were followed for six months after surgery. Results This study included 18 patients with intraconal cavernous hemangioma, ten females (55.6%) and eight males (44.4%) with a mean age 35.6 years. All lesions were located in the intraconal space, eight cases (44.5%) were lateral to the optic nerve, four cases (22.2%) were above the optic nerve, and six cases (33.3%) were below the optic nerve. Postoperative complications included three cases (16.7%) that showed postoperative diplopia due to lateral rectus paresis that improved in all cases within six months, one case (5.6%) that showed postoperative retrobulbar hemorrhage and proptosis that resolved within two weeks without sequelae, and four cases (22.2%) that showed subconjunctival hemorrhage, which resolved within two weeks. Of the two cases with drop of visual acuity preoperative, one case (5.6%) showed improvement of visual acuity and one case (5.6%) did not improve. Conclusions Transconjunctival cryo-assisted extraction of intraconal cavernous hemangioma represents a safe more conservative and effective technique.

Background: The growing middle-class population of Ghana has seen more people being employed in visually demanding occupations  and hence there is an increased desire for quality post-cataract surgical visual outcomes. This study aimed at comparing the outcomes of manual small incision cataract surgery (MSICS) and phacoemulsification (PHACO) among Ghanaians. Methods: This was a retrospective cross-sectional study in which records of patients who underwent MSCIS or phacoemulsification by the same surgeon were reviewed. Results: Medical records of 248 eyes were reviewed, out of which 132 underwent PHACO and 116 had MSICS. A significant number of the  PHACO group had good (6/6–6/18) uncorrected visual acuity (UCVA) compared to the MSICS group at 1–2 weeks follow-up (p = 0.003) and 4–6 weeks follow-up (p = 0.002). MSICS resulted in a higher total astigmatic change compared to PHACO (p < 0.001). The PHACO grouphad a higher number of postoperative complications compared with the MSICS group (p <0.001). Postoperative borderline and poor  uncorrected visual acuity were associated with age, total astigmatic change, and postoperative complications. Conclusion: The postoperative UCVA outcomes at 4–6 weeks’ follow-up indicates that PHACO resulted in noticeably less spectacle dependency when compared to MSICS.

Purpose.To evaluate prospectively the safety and efficacy of optimal keratoplasty for the correction of hyperopia and presbyopia.Methods. Consecutive patients undergoing bilateral optimal keratoplasty for refractive presbyopic and hypermetropic corrections were enrolled. Each patient received a complete ophthalmologic examination at baseline, 1 hour, 1 day, 1 week, 1 month, 3 months, and 6 months after treatment.Results. The study included 40 consecutive eyes of 20 patients. All patients reached the 6-month follow-up. No serious intra- or postoperative complications were recorded. Monocular and binocular uncorrected near visual acuities improved significantly during the follow-up (p<0.001). Binocular uncorrected distance visual acuity in presbyopic patients improved from 0.28 logMAR to a maximum of 0.04 logMAR (from 20/38 to 20/22 Snellen equivalent) the day after the treatment and remained significantly better than baseline until the end of the follow-up. A significant improvement of patient satisfaction for near (p<0.001) and distance (p=0.007) activities was seen the day after treatment and was maintained throughout the follow-up.Conclusions.Optimal keratoplasty is a safe, noninvasive, rapid, pain-free, office-based procedure. It offers low to moderate hyperopes and presbyopes an improvement in uncorrected near visual acuity while maintaining or improving their distance visual acuity.

The study is a retrospective analysis of 51 patients (76 eyes) with primary open-angle glaucoma (POAG) who admitted to our hospital from 2008 to 2010 to analyze the efficacy of trabeculectomy in combination with 5-fluorouracil- (5-FU-) soaked amniotic membranes for the treatment of POAG patients. Among them, 30 patients (41 eyes) were treated with trabeculectomy in combination with 5-FU-soaked amniotic membrane and 21 patients (35 eyes) were treated with trabeculectomy in combination with MMC. Preoperative and postoperative intraocular pressures (IOP), cup/disc ratio, visual acuity and postoperative macular OCT, complications, treatment, and number of corneal endothelial cells were measured, recorded, and analyzed. At the end of 2 years of follow-up, IOP of 36 (87.8%) eyes of patients in the 5-FU group and IOP of 28 (80%) eyes of patients in the MMC group were ≤21 mmHg and patients in the 5-FU group had more stable IOP than patients in the MMC group. During the two years of follow-up, the visual acuity of 22 (53.7%) eyes in the 5-FU group remained unchanged or even improved. Trabeculectomy in combination with 5-FU-soaked biological amniotic membranes can be a surgical option for POAG patients.
