RESUMO
AIM:To evaluate the long-term clinical efficacy of Shotfile software for the myopia patients with presbyopia.METHODS:A total of 43 cases (82 eyes) over the age of 35 myopia patients were treated with laser corneal surgery in our hospital,added Shotfile software at the same time,and followed up for 3a.The uncorrected visual acuity(the distance and near vision),diopter change and visual satisfaction rate were observed at 1,2 and 3a after operation.RESULTS:At 1a after operation,there were 81 eyes (99％) with the uncorrected distance visual acuity reached the preoperative best corrected visual acuity,and 75 eyes (91％) with the uncorrected near visual acuity above 0.66,the average value of the spherical equivalent was (-0.64±0.63)D,the overall satisfaction rate was 91％.At 2a after operation,there were 79 eyes (96％) with the uncorrected distance visual acuity reached the preoperative best corrected visual acuity,and 69 eyes (84％) with the uncorrected near visual acuity above 0.66,the average value of the spherical equivalent was (-0.62±0.59) D,the overall satisfaction rate was 86％.At 3a after operation,There were 77 eyes (94％) with the uncorrected distance visual acuity reached the preoperative best corrected visual acuity,and 62 eyes (76％) with the uncorrected near visual acuity above 0.66,the average value of the spherical equivalent was (-0.55 ± 0.56) D,the overall satisfaction rate was 81％.Intraoperative or postoperative serious complications were not found in all the cases,1 eye of spherical equivalent with-10.0D was found-1.75D back after 1a,respected the willingness of patient for the second correction.CONCLUSION:Shotfile software for the patients myopia with presbyopia is safe and stable in the long-term clinical treatment,and the patient satisfaction is higher,but the near visual ability of some patients may be weakened with the prolongation of time,preoperative communication with patients should be fully.
RESUMO
<p><b>OBJECTIVE</b>Considering the difficulty in classifying some cases with eye trauma by Birmingham Eye Trauma Terminology (BETT) in our epidemiological study, we introduce a new classification for epidemiological study of mechanical eye injuries based on BETT.</p><p><b>METHODS</b>A retrospective investigation was carried out in 31 hospitals from January 2005 to December 2010. All medical records of inpatients with eye injuries were reviewed. A total of 10 718 patients (11 227 eyes) were diagnosed as mechanical eye injuries. All mechanical eye injuries were tried to be classified using BETT. While some eye injuries were difficult to categorize. We recorded the injury type and case number. A new classification based on BETT was also used for the same project.</p><p><b>RESULTS</b>Of 10 718 patients (11 227 eyes) with mechanical eye injuries, the following cases cannot be classified by BETT: 1 488 patients (1 559 eyes) with merely orbital or ocular adnexa injury, 1 961 (2 054) globe injuries associated with orbital or ocular adnexa injury, 271 (284) ocular surface foreign body (OSFB) or ocular wall foreign body (OWFB), 77 (89) contusion, 9 (11) lamellar laceration associated with OSFB or OWFB, 29 (30) rupture associated with OSFB, OWFB or intraocular foreign body and 60 (62) lace- ration associated with OSFB or OWFB. While according to our new classification, all eye injuries can be categorized without any difficulty.</p><p><b>CONCLUSION</b>Difficulty in classifying some eye injuries in epidemiological study by BETT brings some trouble to our study, which can be solved by our new eye injury classification to some extent. It is hoped that other ophthalmologists present better ones to make the classification more perfect.</p>
